Value Collection R57900789 Slotted Spring Pin 30mm 8mm Steel

Product Description

The VALUE COLLECTION R57900789 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 during insertion and exert radial force against the bore wall, creating a secure, vibration-resistant fit without the need for adhesives or locking hardware. This pin measures 30 mm in overall length and 8 mm in diameter, making it suited for medium-duty assemblies requiring a reliable metric fastener. It is installed by machinists, millwrights, and maintenance technicians in manufacturing, mechanical assembly, and industrial equipment maintenance applications.

This slotted spring pin is designed for use in metric assemblies where a through-hole or blind-hole pin retention solution is required. Typical applications include shaft-to-hub connections, linkage assemblies, hinge pivots, and alignment fixtures. The 1070-1080 carbon steel construction provides adequate tensile strength and spring-back characteristics for general industrial use. This pin does not meet military specifications and is intended for commercial and industrial applications. It is sold individually, with a minimum order quantity of 50 units.

Key Features

• Slotted design allows radial compression for secure interference fit in standard bored holes
• 1070-1080 carbon steel grade provides reliable spring-back force and shear resistance
• Plain finish suitable for indoor and controlled-environment industrial assemblies
• Metric dimensioning: 30 mm length and 8 mm diameter for compatibility with metric-toleranced bores
• Minimum order quantity of 50 units supports production and maintenance stocking needs

Compatibility

Designed as a standard metric slotted spring pin for use in commercial and industrial assemblies requiring an 8 mm bore diameter and 30 mm pin length.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. The receiving bore should be drilled and reamed to the appropriate tolerance for the pin diameter before installation. Ensure the assembly is de-energized and secured before driving the pin. Avoid reusing a slotted spring pin that has been removed, as repeated compression cycling can reduce holding force.
