Value Collection R57001054 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R57001054 is a hex socket cap screw designed for fastening applications that require a recessed drive and strong clamping force. It features a 3/8-16 UNC thread and a 3.25-inch length under head, making it suitable for medium-duty structural and mechanical assembly work. The screw is machined from 18-8 stainless steel, which provides corrosion resistance in wet or mildly corrosive environments. Drive engagement is through a 5.16-inch hex socket, requiring a matching Allen key or hex bit. This fastener is commonly installed by maintenance technicians, pipefitters, and mechanical contractors working on equipment assemblies and structural connections.

This hex socket cap screw is used across a wide range of industrial and mechanical applications, including equipment mounting, pump and valve assembly, and general fabrication work. The 3/8-16 UNC coarse thread is a standard size suited for use in steel, aluminum, or threaded inserts in both light commercial and industrial settings. The bright, uncoated finish is appropriate for indoor applications or environments where stainless steel alone provides adequate corrosion resistance. Minimum order quantity is 5 pieces per order.

Key Features

• 3/8-16 UNC coarse thread for standard compatibility with matching nuts and threaded inserts
• 3.25-inch length under head provides adequate grip length for medium-depth fastening applications
• 18-8 stainless steel construction offers corrosion resistance without additional coatings
• Bright, uncoated finish maintains tight dimensional tolerances for precision fit
• Hex socket drive accepts standard 5/16-inch Allen key or hex bit

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw compatible with any application requiring a 3/8-16 coarse-thread fastener with a 5/16-inch hex socket drive and 3.25-inch length under head.

Installation Notes

Install using a 5/16-inch hex key or hex socket bit. Ensure the mating threads are clean and free of debris before driving the screw to prevent galling, which is a known risk with stainless steel fasteners. Apply an anti-seize compound to the threads if repeated disassembly is anticipated. Follow applicable mechanical or structural codes for torque requirements based on joint design.
