RS PRO 374-042 4 mm Diameter Galvanised Steel Slotted Spring Pin is a high-quality tension pin engineered for mechanical fastening applications. Manufactured from galvanised steel, this slotted spring pin provides robust corrosion resistance, ensuring durability in industrial environments.
This spring pin, conforming to DIN Standard 1481 and ISO 8752 length tolerances, functions as a self-retaining fastener for securing machine parts. Its single coil of spring steel with an open slot reduces diameter during insertion, allowing a tight fit within appropriately sized drilled holes. Such tension pins act effectively as locating dowels or retaining pins, delivering positive locking action in holes produced to typical manufacturing tolerances.
The product is supplied in packs consisting of four different lengths, each pack containing an equal quantity of each size for flexible application requirements in assembly and repair work.
These pins are widely used in various industrial sectors including mechanical manufacturing, automotive assembly, fluid power systems, and general machinery maintenance. The galvanised finish improves resistance to environmental factors, extending the service life of the fasteners in demanding conditions.
An additional feature for increased strength involves inserting a smaller diameter pin inside a larger outer pin to enhance retention strength. However, care must be taken to offset the slot positions between the pins for optimal performance.
The pin material is galvanised steel for corrosion resistance. Complies with DIN 1481 and ISO 8752 standards. Slotted spring design allows compression on insertion. Suitable for securing machine parts and assemblies. Supplied in multi-length packs with equal quantities.
Ideal for use as locating dowels or retaining pins. Designed to fit in plain drilled holes with normal tolerances. Usable across mechanical, fluid power, and industrial repair applications.
