Value Collection R57700657 Slotted Spring Pin 18-8 Ss

Product Description

The VALUE COLLECTION R57700657 is a slotted spring pin machined from 18-8 stainless steel, designed to secure components through interference fit in drilled holes. At 3-1/2 inches long and 3/8 inch in diameter, it provides reliable axial and radial retention in assemblies where corrosion resistance and moderate spring tension are required. The slotted design allows the pin to compress during installation, distributing stress along its length and absorbing shock loads. Fabricated in the inch measurement system, this pin suits a wide range of mechanical assembly and maintenance applications across industrial, marine, and commercial environments.

Slotted spring pins are used in mechanical assemblies where components must be pinned in position while allowing for slight misalignment or vibration. Common applications include shaft-to-hub connections, clevis linkages, hinges, and general fastener retention in equipment maintenance and repair. The 18-8 stainless steel construction makes this pin well suited for environments exposed to moisture, mild chemicals, or temperature cycling. Machinists, millwrights, and maintenance technicians working in food processing, marine, or outdoor equipment applications frequently specify stainless spring pins for long service life.

Key Features

• Slotted design compresses on installation for secure interference fit
• 18-8 stainless steel construction provides corrosion resistance in wet or chemically active environments
• 3-1/2 inch overall length suits deep-hole pinning applications
• 3/8 inch diameter fits standard drilled pin holes
• Inch measurement system for compatibility with standard imperial tooling

Compatibility

Designed as an OEM-style replacement or standard replacement slotted spring pin for mechanical assemblies requiring a 3/8 inch diameter by 3-1/2 inch slotted pin in 18-8 stainless steel.

Installation Notes

Slotted spring pins are installed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. The receiving hole should be drilled to the nominal pin diameter to achieve proper interference fit. Ensure the assembly is de-energized and any rotating shafts are locked out before installation or removal per OSHA lockout/tagout procedures. Do not reuse a spring pin that has been removed, as the slotted body may not return to its original diameter.
