RS PRO 3 mm Diameter Galvanised Steel Slotted Spring Pin 374-020

The RS PRO 374-020 3 mm Diameter Galvanised Steel Slotted Spring Pin offers a resilient and effective fastening option for precision engineering and general mechanical use. Designed for positive locking in plain drilled holes, this spring pin is constructed from high-grade galvanised steel, delivering outstanding resistance to corrosion and extended service life even in challenging environments.

The slotted spring design allows the pin to compress upon installation, maintaining consistent tension and ensuring parts remain securely fixed. Its primary function is to serve as a self-retaining fastener, which is ideal for both industrial machinery assembly and maintenance tasks. This model features a 3 mm diameter and is typically supplied in packs comprising various lengths - such as 10 mm, 16 mm, 24 mm, and 30 mm - to suit a wide variety of positioning and retaining needs in mechanical assemblies.

RS PRO's precision engineering standards guarantee that each pin meets DIN 1481 and RoHS compliance, making it suitable for regulated environments where quality assurance is critical. The zinc-plated finish further protects against abrasion and corrosion, supporting reliable service in industrial, manufacturing, and workshop applications.

Ideal uses include acting as locating dowels or retaining pins, particularly in scenarios where repetitive removal and replacement are required. The pins are designed for installation in holes drilled to standard tolerances, allowing a positive locking action without the need for tightening hardware, adhesives, or other complex securing mechanisms.

Supplied in carefully balanced packs, users benefit from having equal quantities of each available length, facilitating assembly versatility and streamlining inventory management for maintenance teams. The modular format also allows for enhanced strength in certain applications by nesting a smaller-diameter spring pin inside a larger pin, as long as the slots are not aligned.

Whatever your industry - be it machine building, toolmaking, automotive, repair operations, or general industrial fabrication - these slotted tension pins are engineered for ease of use and long-term performance. Their robustness and adaptability make them a preferred choice for professionals needing secure, removable fasteners that provide lasting structural integrity.
