Value Collection R57900649 Slotted Spring Pin 18mm 4mm Steel

Product Description

The VALUE COLLECTION R57900649 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins are cylindrical fasteners with a longitudinal slot that allows the pin to compress upon insertion, creating a secure interference fit within a drilled hole. This pin measures 18 mm in length and 4 mm in diameter, following the metric system of measurement. It is commonly installed by maintenance technicians, millwrights, and assemblers in machinery, equipment frames, and mechanical assemblies where a removable yet firmly seated fastener is required.

This slotted spring pin is suited for general industrial and mechanical assembly applications where metric fasteners are specified. The 1070-1080 carbon steel construction provides adequate shear strength and resilience for moderate-load applications. The plain finish indicates no additional corrosion coating, making this pin appropriate for interior or dry-environment applications. It is sold individually but requires a minimum order quantity of 100 units, making it practical for production assembly, maintenance stockrooms, and bulk fastener replenishment.

Key Features

• Slotted design allows radial compression for secure interference fit in drilled holes
• 1070-1080 carbon steel construction for reliable shear strength in mechanical assemblies
• 18 mm overall length and 4 mm diameter in metric sizing
• Plain finish suitable for controlled or indoor environments
• Sold per piece with a minimum order quantity of 100 units

Compatibility

Designed as a general-purpose metric slotted spring pin for mechanical assemblies, machinery, and equipment requiring a 4 mm diameter, 18 mm long interference-fit pin fastener.

Installation Notes

Slotted spring pins are typically installed using a pin punch and hammer or an arbor press to drive the pin into a pre-drilled hole sized to the nominal pin diameter. Ensure the receiving hole is clean, free of burrs, and dimensionally correct before installation. De-energize and lock out any machinery before servicing components that require pin removal or installation. Do not attempt to install spring pins in holes that are undersized, as this can cause cracking or improper seating.
