Value Collection R57900661 Slotted Spring Pin 30mm 4mm Steel

Product Description

The VALUE COLLECTION R57900661 is a slotted spring pin manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins are hollow, longitudinally slotted fasteners that compress upon insertion and exert radial spring force against the walls of a drilled hole, creating a secure, vibration-resistant connection without threads. This pin measures 30 mm in length and 4 mm in diameter, making it suited for light-to-medium duty retention and alignment applications. It is installed by machinists, maintenance technicians, and assembly workers in production and field-repair environments where precise hole engagement and reliable retention are required.

This slotted spring pin is appropriate for metric fastening applications in mechanical assemblies, machine components, hinges, linkages, and shaft-to-hub connections. The 1070-1080 steel construction provides good tensile strength and spring characteristics suitable for general industrial use. The plain finish is standard for interior or protected applications where corrosion exposure is minimal. This pin is sold individually but carries a minimum order quantity of 100 units, making it a practical choice for production runs, maintenance stock, or assembly line replenishment.

Key Features

• Slotted design compresses on insertion and exerts consistent radial spring force against bore walls
• 1070-1080 steel grade delivers reliable tensile strength and spring retention characteristics
• 30 mm overall length and 4 mm diameter in metric sizing for standard metric hole patterns
• Plain finish suitable for interior, lubricated, or protected installation environments
• UNSPSC Code 31163201 for procurement and catalog classification

Compatibility

Designed as a general-purpose metric slotted spring pin for use in mechanical assemblies requiring a 4 mm diameter hole and 30 mm pin engagement depth.

Installation Notes

Slotted spring pins are typically installed by machinists or mechanical assemblers using a pin punch and hammer or an arbor press. The receiving hole should be drilled to the correct nominal diameter per standard metric tolerances before installation. Always de-energize, depressurize, or lock out the equipment being serviced before driving or removing spring pins. Avoid reusing a spring pin that has been removed, as repeated compression cycles can reduce retention force.
