Value Collection MP42834 Spring Pin 20mm 5mm Metric 50-pack

Product Description

The VALUE COLLECTION MP42834 is a metric spring pin designed for use in light-duty fastening and alignment applications across mechanical assemblies. Spring pins, also called slotted or roll pins, are hollow cylindrical fasteners that compress during installation and expand to grip the bore wall, providing a secure, vibration-resistant connection without threading. This pin measures 20 mm in overall length with a 5 mm diameter, conforming to metric sizing standards. It is typically installed by maintenance technicians, millwrights, and mechanical assemblers working on machinery, hinges, linkages, and similar light structural or mechanical connections.

This spring pin suits metric-dimensioned assemblies in industrial maintenance, general manufacturing, and mechanical repair environments. The 20 mm length and 5 mm diameter make it a common fitment for hinges, clevis pins, shaft-to-hub connections, and alignment fixtures where a removable or semi-permanent pin is required. It ships in a pack quantity of 50 units, making it practical for shop-floor stocking or service-van kit replenishment. The metric sizing is appropriate for equipment manufactured to ISO or DIN standards.

Key Features

• 20 mm overall length in metric sizing for ISO and DIN-compliant assemblies
• 5 mm diameter provides a common fit for standard metric bores and linkage components
• Spring-pin design compresses on insertion for a friction-fit, vibration-resistant hold
• Pack quantity of 50 units supports bench stock and service kit replenishment
• No threading required — installs with a punch and hammer or arbor press

Compatibility

Designed as a general-purpose metric spring pin for mechanical assemblies, linkages, hinges, and alignment fixtures requiring a 5 mm diameter, 20 mm long roll pin in metric-dimensioned equipment.

Installation Notes

Spring pins are installed by mechanical technicians and millwrights using a pin punch and hammer or an arbor press. De-energize and lock out all machinery before installing or removing pins from live assemblies. Ensure the receiving bore diameter matches the pin nominal diameter to achieve proper interference fit. Do not reuse spring pins that have been fully expanded or deformed, as fatigue cracking can occur.
