Value Collection R57900607 Slotted Spring Pin 12mm 3.5mm

Product Description

The VALUE COLLECTION R57900607 is a slotted spring pin designed for use in mechanical assemblies where a secure, removable fastener is needed in a drilled hole. Manufactured from 1070-1080 steel with a plain finish, this pin measures 12 mm in overall length and 3.5 mm in diameter. The slotted design allows the pin to compress during insertion and expand inside the bore, creating a firm, vibration-resistant fit without permanent deformation of the housing. This type of fastener is a standard choice for machine builders, maintenance mechanics, and industrial assembly technicians working within metric-dimensioned component systems.

This slotted spring pin is suited for use in general-purpose mechanical assemblies, machine components, and equipment requiring metric fasteners. Typical applications include shaft-to-hub connections, hinge mechanisms, locking levers, and light-duty shear applications in industrial machinery. The 1070-1080 steel grade provides adequate hardness and spring-back for repeated installation and removal cycles. This pin is sold individually but requires a minimum order quantity of 100 units, making it appropriate for production runs, maintenance stocking, or assembly line use.

Key Features

• Slotted design compresses on insertion for a secure, self-retaining fit in drilled bores
• 1070-1080 steel construction provides reliable spring-back and resistance to shear loads
• Plain finish suitable for dry or lightly lubricated environments
• Metric dimensions: 12 mm overall length, 3.5 mm diameter
• UNSPSC Code 31163201 for streamlined procurement and catalog classification
• Does not meet military specifications — intended for standard commercial applications

Compatibility

Designed as an OEM-style replacement or standard-stock slotted spring pin for metric mechanical assemblies requiring a 3.5 mm diameter pin in a 12 mm bore depth.

Installation Notes

Installation is typically performed by maintenance mechanics or machine assembly technicians using a pin punch and hammer or a press. Always de-energize and lock out equipment before servicing components that contain spring pins. Drive the pin squarely into the bore to avoid cocking or deforming the slot. Use a pin punch sized to the pin diameter to seat or remove the pin without damaging the host material.
