Value Collection R57001226 Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R57001226 is a partially threaded hex head cap screw designed for general industrial and mechanical fastening applications. Manufactured from 18-8 stainless steel, this fastener delivers reliable corrosion resistance in wet, outdoor, and chemically exposed environments. It features a 3/8-16 UNC thread size with a 7-1/2-inch length under head, making it suited to applications requiring a longer grip length without full-thread engagement. The uncoated finish maintains dimensional accuracy for precision fits. This fastener is installed by millwrights, maintenance technicians, pipefitters, and general mechanical tradespeople across a wide range of industries.

This cap screw is appropriate for structural and mechanical assemblies where corrosion resistance is a priority and a partially threaded shank is required to bear shear loads or align mating components. Common applications include equipment mounting, machinery assembly, marine hardware, food-processing equipment, and other environments where stainless fasteners are specified. The inch-measurement system and UNC thread standard make it compatible with standard American hex drivers and wrenches.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and chemically active environments
• Partial threading allows the unthreaded shank to carry shear loads and align components
• 3/8-16 UNC thread standard compatible with standard American tooling
• 7-1/2-inch length under head suits deep-stack or long-grip fastening applications
• Uncoated finish maintains close dimensional tolerances for precision assembly

Compatibility

Designed as a standard-dimension inch-series hex head cap screw suitable for any application specifying a 3/8-16 UNC partially threaded fastener in 18-8 stainless steel.

Installation Notes

Install using a standard 9/16-inch hex wrench or socket driver appropriate for a 3/8-inch hex head cap screw. Ensure mating threads are clean and free of debris before installation. Apply anti-seize compound when joining stainless-to-stainless hardware to prevent galling. Torque to the value specified in the applicable engineering or equipment documentation.
