Value Collection R57900667 Slotted Spring Pin 40mm 4mm Steel

Product Description

The VALUE COLLECTION R57900667 is a slotted spring pin manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins are cylindrical fasteners with a longitudinal slot that allows the pin to compress during insertion and exert radial force against the bore wall, creating a secure, vibration-resistant fit without adhesives or secondary locking hardware. This pin measures 40 mm in overall length and 4 mm in diameter. It is a metric-dimensioned component suited for mechanical assemblies where controlled retention force and ease of installation are required. Maintenance technicians and mechanical assembly professionals typically install these pins in production and service applications.

Slotted spring pins are used across a wide range of mechanical assemblies including linkages, hinges, shafts, and housings in industrial, agricultural, and general machinery. This pin is a metric component and is dimensioned to fit metric-standard bored holes. It does not meet military specifications, making it appropriate for standard commercial and industrial applications rather than MIL-SPEC-governed assemblies. Sold as a single pin per package with a minimum order quantity of 100 units.

Key Features

• 40 mm overall length suits medium-depth bore applications
• 4 mm diameter for metric-standard bore fitment
• 1070-1080 grade steel construction provides reliable spring tension and durability
• Slotted design allows radial compression for secure, self-retaining installation
• Plain finish with no coating or plating
• Does not meet military specifications — suited for standard commercial and industrial use

Compatibility

Designed as a standard metric slotted spring pin replacement for mechanical assemblies requiring a 4 mm diameter, 40 mm long spring pin in commercial or industrial service.

Installation Notes

Slotted spring pins are installed by mechanical technicians using a pin punch and hammer or a press, driving the pin into a properly sized drilled hole. Ensure the bore diameter matches the nominal pin diameter to achieve correct retention force. De-burr the hole entry before installation to prevent pin distortion. Always relieve any load or motion from the assembly before removing or installing spring pins.
