Value Collection R57900665 Slotted Spring Pin 35mm 4mm Steel

Product Description

The VALUE COLLECTION R57900665 is a slotted spring pin designed for use in mechanical assemblies where a fastener must flex slightly to accommodate tolerance variations in the mating hole. Manufactured from 1070-1080 grade steel with a plain finish, this metric pin measures 35 mm in length and 4 mm in diameter. The slotted design allows the pin to compress during installation and exert a radial spring force against the hole wall, providing a secure, vibration-resistant fit without requiring adhesives or secondary locking hardware. Machinists, millwrights, and mechanical assembly technicians install these pins in a wide range of production and maintenance applications.

Slotted spring pins are suited for use in shaft-to-hub connections, linkage assemblies, hinge pivots, and general mechanical fastening tasks where repeated removal and reinstallation may be required. This pin follows a metric dimensional standard and is appropriate for use in equipment manufactured to metric tolerances. It does not meet military specifications. Sold individually, with a minimum order quantity of 100 units, making it well suited for production line stocking or MRO inventory programs.

Key Features

• Slotted spring design provides radial clamping force against the bore wall for a secure, self-retaining fit
• 1070-1080 steel construction delivers hardness and strength suitable for moderate-load fastening applications
• Plain finish — no coating or plating — for straightforward dimensional compliance
• Metric dimensioning: 35 mm overall length, 4 mm diameter
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed for use in mechanical assemblies requiring a metric 4 mm slotted spring pin. Verify bore diameter and tolerance in the mating component before installation to ensure proper spring engagement and retention.

Installation Notes

Slotted spring pins are installed by machinists or mechanical technicians using a pin punch and hammer or a hydraulic press, depending on assembly requirements. The receiving bore should be sized to the appropriate tolerance for the pin diameter to achieve correct spring force. Always de-energize and lock out any equipment before servicing pinned assemblies. Avoid reusing pins that have been visibly deformed or fatigued, as spring force and retention may be compromised.
