Value Collection R40682243 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R40682243 is a partially threaded hex socket cap screw designed for secure fastening in mechanical, structural, and industrial assemblies. It features a 3/8-16 UNC thread and measures 3 inches in length under the head. The drive is a 5/16 inch hex socket (Allen) type, suited for torque-critical applications where a flush or recessed fastener head is required. Constructed from 18-8 stainless steel, this screw provides corrosion resistance in wet, outdoor, and chemically exposed environments. Licensed tradespeople, maintenance technicians, and fabricators working in HVAC, plumbing, and general mechanical service rely on this fastener grade for reliable clamping force.

This cap screw is appropriate for light to medium-duty fastening applications across residential, commercial, and industrial settings. It is commonly used in equipment panels, brackets, flanges, and mechanical housings where a recessed hex drive is preferred over an exposed hex head. The partial threading allows for clamping without thread engagement along the full shank length, which is useful when joining thick material stacks or where shear strength across the unthreaded shank is a design consideration.

Key Features

• 3/8-16 UNC thread size for compatibility with standard inch-series tapped holes
• 3 inches length under head for use with thicker material assemblies
• Partial threading provides a smooth shank section for improved shear load handling
• 5/16 inch hex socket drive for use with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments

Compatibility

Designed as a standard replacement or original-installation fastener for any 3/8-16 UNC tapped hole application requiring a hex socket cap screw with a 3-inch length under head.

Installation Notes

Installation is performed using a 5/16 inch hex key or Allen-type socket bit driver. Verify that the mating tapped hole is clean and free of debris before threading. Power down or de-energize any equipment before accessing fastened assemblies on live electrical or mechanical systems. Follow applicable industry codes and equipment manufacturer torque guidance for the specific assembly.
