Value Collection R57900811 Slotted Spring Pin 90mm 8mm Steel

Product Description

The VALUE COLLECTION R57900811 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins are cylindrical fasteners with a lengthwise slot that allows radial compression during installation, enabling the pin to exert outward spring force against the bore wall for a secure, vibration-resistant fit. This pin measures 90 mm in length with an 8 mm diameter, making it suited for medium-duty assembly and alignment applications across a wide range of mechanical and industrial equipment. Installation is typically performed by maintenance technicians and assembly professionals working in manufacturing, general industrial, or MRO environments.

This slotted spring pin is used in shaft-to-hub connections, hinge assemblies, clevis linkages, and general mechanical alignment tasks where a press-fit or driven pin is required. The metric dimensions make it appropriate for equipment and machinery designed to metric specifications. It is sold individually but requires a minimum order quantity of 25 units per order, which suits shop-stock replenishment and production-floor applications where these pins are consumed in volume.

Key Features

• 1070-1080 grade carbon steel construction for reliable strength in standard industrial applications
• Slotted design allows radial compression for self-retaining installation without adhesive or secondary fasteners
• 90 mm overall length with 8 mm diameter in metric sizing
• Plain finish suitable for indoor mechanical assemblies not subject to heavy corrosive exposure
• Minimum order quantity of 25 units supports production and shop-stock usage

Compatibility

Designed as a general-purpose metric slotted spring pin for use in any bore or through-hole application requiring an 8 mm diameter pin with a 90 mm length.

Installation Notes

Slotted spring pins are installed by driving them into a drilled bore using a pin punch and hammer or an arbor press. The bore diameter should match the nominal pin diameter per applicable engineering standards to ensure proper retention. Always de-energize and lock out any machinery before servicing pin connections in rotating or reciprocating assemblies. Avoid re-using a spring pin that has been previously driven, as repeated installation cycles can reduce the spring tension and retention force.
