Value Collection R57900681 Slotted Spring Pin 12mm 5mm Steel

Product Description

The VALUE COLLECTION R57900681 is a metric 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 radial compression during insertion, creating a secure interference fit in the mating hole. This pin measures 12 mm in overall length and 5 mm in diameter, making it suited for light- to medium-duty retention and alignment applications in mechanical assemblies. Machinists, maintenance technicians, and assembly professionals install these pins using a press or pin punch. The 1070-1080 steel construction provides adequate hardness and spring-back force for general industrial use.

Slotted spring pins are used across a wide range of mechanical and industrial applications including hinges, linkage assemblies, shaft-to-collar connections, and machinery fixtures. This metric-dimensioned pin is appropriate for assemblies designed to ISO and metric engineering standards. It is commonly installed in both light manufacturing and maintenance-repair-overhaul (MRO) environments where a reliable, reusable retention pin is required. Sold individually, with a minimum order quantity of 100 pieces per order.

Key Features

• Slotted design allows radial compression for a secure interference fit in drilled holes
• 12 mm overall length and 5 mm diameter — metric sizing for ISO-standard assemblies
• 1070-1080 grade steel construction provides hardness and reliable spring-back retention force
• Plain finish suitable for dry or lightly lubricated installation environments
• Minimum order quantity of 100 units supports production and MRO stocking needs

Compatibility

Designed as a general-purpose metric slotted spring pin for use in any mechanical assembly requiring a 5 mm diameter, 12 mm long retention or alignment pin in a drilled or reamed through-hole.

Installation Notes

Installation is typically performed by machinists or mechanical assembly technicians using a pin punch and hammer or an arbor press. Ensure the receiving hole is drilled or reamed to the correct tolerance for the pin diameter before installation. The pin should be driven straight and square to the hole axis to prevent cocking or deformation of the slot. Removal requires a punch slightly smaller than the pin diameter driven from the accessible end.
