Description/Basics

The screwed connection is one of the most commonly used methods among the soluble compounds. Due to their flat head, flathead screws have various advantages over conventional screws.

Screws with a flat head are often utilised in places that need to form a flat level as much as possible.
Due to their head geometry, flathead screws allow counterbores to be made less deep or completely omitted. This allows covers to be made thinner walls and thus save weight. These advantages also result in cost savings through material savings and the elimination or shortening of production steps. The MISUMI flat-head screws are thus ideal for mounting sheet metal, thin panels, housing covers and other covers.
As opposed to the head form of commercially available screws, the flathead screw reduces the risk of injury at accessible locations, such as housing covers, mounting flaps, etc. This also eliminates the frequently required plastic caps on large screw heads.

Contrary to the standard flathead screws (DIN 921, DIN 922 and DIN 923), MISUMI has flathead screws with hexagon socket, hexagon socket (Torx) and external hexagon. These drive types reduce slipping during assembly compared to typical cross or slotted drives.

MISUMI offers flathead screws in various strength classes.
However, due to the delicate head of flathead screws, the strength on the head can be lower than that on the thread, since there is less material available. The respective strength class is therefore assigned to the individual flathead screws (see Basic Properties).

 

Areas of Application

Flathead screws are intended for fastening of joining parts. Often, the flathead screws are used for housing covers or in applications requiring low weight.
Thanks to the multi-selectable surface treatments, flathead screws are particularly resistant to environmental influences. This allows flathead screws to be used in almost all industry sectors of plant engineering and mechanical engineering.
The benefits of using flathead screws are versatile. The main advantages of flathead screws are their low weight and space savings.
To utilise a flathead screw with vent function, e.g., for pressure equalization, MISUMI also offers hollow screws with a flat head.

Materials

 

Strength classes

The strength class gives the tensile strength [R m ] and yield strength [R e ], or expansion limit [R p-0.2] of the screw.
Screws that are subject to a strength class are often marked by the strength class on the screw head. For some screws, the reference to the strength class is missing. In such cases, please refer to the Screw Data Sheet (see Basic Properties).
The screw strength class is an indication of the tensile strength and the expansion limit of a screw. The higher the specification of the strength class, the higher the tensile strength and expansion limit. In principle, a distinction is made between steel and stainless steel (stainless steel).
Stainless steel screws are marked with the letters A, C and F (e.g., A2-50). Steel screws are marked with two numbers, separated by a dot (e.g., 8.8).
The tensile strength and elongation limit can be determined based on this information. Which of the two values and safety number are used for the further calculation of the screws depends on the applied load case.

Example of a strength marking

 

Tensile strength steel

Example: 8.8

R m = 8 x 100 N/mm 2 = 800 N/mm 2

The expansion limit of the screw material is the resistance value that can be applied to the material without permanent deformation. Thus, the screw can return to its original length after this stress (elastic range).
If the elastic range is exceeded, there is a permanent (plastic) deformation, which can end in a tear/fracture of the material upon further stress.
To determine the value, both values of the strength specification are multiplied with each other and additionally by a factor of 10.

Example 8.8

R p-0.2 = 8 x 8 x 10 N/mm 2 = 640N /mm 2

 

Tensile strength stainless steel

For stainless steel screws, the strength specification begins with the specification of the material group used.
The most common stainless steel screw is the A2 stainless steel screw, which is manufactured from (colloquially speaking) V2A material. In this example, the A2 screw is made of austenitic stainless steel.
Ferritic stainless steel screws are often marked with a [F] at the beginning and martensitic stainless steel types with a [C].
Unlike the steel screws, the second value of the strength specification is multiplied by a factor of 10 for the stainless steel screws in order to determine the tensile strength of the screw material. The expansion limit [R p-0.2] must be determined in tabular form based on the expansion limit of the raw material or the manufacturer.

Example A2-50

R m = 50 x 10 N/mm 2 = 500 N/mm 2

Screws without specification of this strength classification have manufacturer-bound values that must be taken from the respective data sheets or manufacturer information. This often occurs with screws with special shape and treatment.

 

Coatings

MISUMI’s flathead screws are available in burnished, chrome-plated, or nickel-plated to best protect them from corrosion.
As an alternative to one of these surface treatments, flathead screws can also be coated with LTBC. The LTBC coating (Low Temperature Black Chrome Platinum) is a surface coating that protects against corrosion and has low reflection. The coating consists of a 5 μm thick chrome ceramic layer with fluoropolymer infusion and forms a black film. In addition, the LTBC coating is resistant to cracking and bending and it is thus resistant to peeling due to extreme or repeated bending. This makes LTBC-coated flathead screws particularly suitable for areas where corrosion or light reflections are undesirable.

 

Dimensions

Compared to an M5 standard cylinder head screw with 5 mm head height, with a flathead screw it is possible to save up to 4 mm of head height.

Frequently Asked Questions (FAQ)

Question:

Do you have any belt pulleys without a hole?

Answer:

The MISUMI toothed pulleys always have a pilot bore. It is expanded depending on your configuration. It provides the advantage that the belt pulleys are already provided with a suitable shaft bore ready for installation. Therefore, it does not require time-consuming post-processing.

Question:

Do you have timing pulleys made of aluminum?

Answer:

The MISUMI online shop also offers timing pulleys or toothed pulleys in aluminum. Furthermore, we are also offering belt pulleys in steel and stainless steel. The return rollers and idler pulleys for the timing belts are also available in plastic.

Question:

Is a transmission with toothed belt pulleys possible?

Answer:

With toothed pulleys, a gear ratio is possible in a drive. The gear ratio is established based on the number of teeth on the belt pulleys. It should be ensured that the minimum number of teeth of the timing pulley disc is not undercut.

Question:

Which type of the toothed belt pulley can be clamped during assembly?

Answer:

There are a number of ways to install timing pulleys on a shaft. For applications that are not exposed to high torque, such as conveyors, it can be sufficient to fasten a timing pulley using clamping threaded pins. For this purpose, the shaft should have a flat surface.
For higher loads, a toothed pulley with a keyway can also be used.
A further variant is the fastening of a timing pulley via a conical chip sleeve. Depending on the type of Mecha lock, the timing pulley requires lateral internal threads, which can be added through additional options in the MISUMI online shop.
A timing pulley with a bore hole can also be combined with a Mech lock. MISUMI is offering this combination as a set.

Question:

Where do you position the tension roller?

Answer:

If an idler pulley should be utilised, it should be positioned on the sag side. This means that the idler pulley is attached to the side not subjected to pull.
Ideally, a toothed idler pulley is mounted on the inside of the toothed belt. The tensioning roller should always be larger than the smallest toothed idler pulley of the belt drive system.
If an idler pulley must tension the toothed belt from the outside, then a non-toothed (flat) idler pulley should be used. Cantilever pins, which MISUMI offers in various geometric versions, are suitable for fastening.

Question:

Which parallel key can be used for the toothed pulleys?

Answer:

The parallel key size is based on the shaft diameter. In this case, it is recommended using the MISUMI parallel keys, as they fit better when MISUMI toothed pulleys are used. See Overview available as PDF for keyway tolerances.

Question:

Is a timing pulley with a round profile better?

Answer:

Timing pulleys and round-profile timing belts are not recommended for every application. For example, the round profile shape is well suited for applications that require high positioning accuracy. Therefore, they are often used in 3D printers and scanners. Compared to other profile shapes, the round profile shape has a higher wear resistance. Another advantage of the round profile shape is the minimized play in the return (reverse play).

Question:

Which belt pulley is suitable for Gates toothed belts?

Answer:

The GT and EV timing pulleys are suitable for Gates’ toothed belts. However, these require you put attention to the slope (distance of the teeth) of the toothed belt. It must be checked whether these correspond to the selected toothed pulley.

Question:

Are the curtain discs necessary for the toothed pulleys?

Answer:

It is recommended using the smaller belt pulleys particularly with curb disc. The curb disk ensures that the toothed belt does not migrate down from the toothed belt pulley. Even with the smallest misalignment of a pulley, there may be a risk that the toothed belt will move and jump during operation.

Question:

How is the gearing of the toothed pulleys manufactured?

Answer:

The gear teeth of the MISUMI toothed belt pulley are mainly pushed. This ensures high manufacturing accuracy. As a result, the teeth fit precisely into the toothed belt profile of the timing belts and ensure optimal power and torque transmission.
