Metal fittings and small accessories are instruments and parts used for measurements, securing, storage, etc., during construction work, plumbing work, installation of electronic equipment, etc. This includes products such as bubble levels to check the horizontal and vertical directions by attaching, securing, etc. to objects, various scales to measure the dimensions and angles of machines and equipment, ground terminals to secure electronic equipment and distribution board parts, and tool belts, etc. to store keys for equipment. Many of the fittings and small accessories are relatively small and feature many products that can be used and attached by hand. In addition, because they are often cases where products are used in situations where high safety is required, there are many products made of metal or resin with excellent corrosion resistance and durability. Depending on the product, rated operating temperature, rated current, contact resistance value, etc. may be set, so prior confirmation is required.
