Value Collection R57900871 Slotted Spring Pin 30mm 12mm Steel

Product Description

The VALUE COLLECTION R57900871 is a slotted spring pin designed for use in mechanical assemblies where controlled radial flexibility and secure retention are required. Manufactured from 1070-1080 grade carbon steel with a plain finish, this metric pin measures 30 mm in overall length and 12 mm in diameter. The slotted design allows the pin to compress during insertion and exert consistent outward spring force against the bore wall, creating a reliable interference fit without additional fasteners. Licensed trades and mechanical assemblers use slotted spring pins in shafts, linkages, and housings across a wide range of industrial and commercial applications.

This slotted spring pin is suited for metric mechanical assemblies in industrial equipment, agricultural machinery, material handling systems, and general manufacturing applications. The 12 mm diameter and 30 mm length make it appropriate for medium-load shaft-to-hub connections, hinge pins, and retaining applications where a standard metric coiled or solid pin is not specified. This part is sold individually per package with a minimum order quantity of 25 units.

Key Features

• Slotted design compresses for press-fit installation and provides consistent spring retention force
• 1070-1080 carbon steel construction for reliable strength in mechanical assemblies
• Plain finish suitable for standard indoor and protected mechanical environments
• Metric sizing: 30 mm overall length, 12 mm diameter
• Does not meet military specifications — intended for standard commercial applications

Compatibility

Designed as a standard metric slotted spring pin for use in mechanical assemblies requiring a 12 mm diameter, 30 mm long retention pin per metric fastener specifications.

Installation Notes

Slotted spring pins are typically installed by mechanical assemblers or maintenance technicians using a pin punch and hammer or an arbor press. Ensure the receiving bore diameter is machined to the appropriate tolerance for the pin diameter before installation. Do not exceed the rated load capacity for the pin diameter and material grade. Always relieve mechanical load from the assembly before removing or replacing a spring pin in service.
