Value Collection R56000918 Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION R56000918 is a hex socket cap screw designed for fastening applications that require a compact, recessed drive profile. Sized at 3/8-24 UNF with a 1-inch length under head, this screw accepts a 5/16-inch hex key drive. It is manufactured from 316 stainless steel with a bright, uncoated finish, providing strong corrosion resistance in wet, chemical-exposed, or marine environments. Typical installers include plumbers, pipefitters, HVAC technicians, and mechanical contractors working on equipment assemblies, brackets, flanges, and structural connections where thread precision and corrosion resistance are priorities.

This screw is suited for use in residential and commercial mechanical systems, marine hardware, food-service equipment, and process piping assemblies. The fine 3/8-24 UNF thread pitch provides tighter thread engagement and greater clamping force compared to coarse-thread equivalents, making it appropriate for applications subject to vibration or where precise torque control is required. It is commonly used in equipment panels, valve assemblies, pump housings, and other mechanical connections requiring a flush or countersunk fastener profile.

Key Features

• 3/8-24 UNF fine thread for high clamping force and vibration resistance
• 1-inch length under head for consistent grip in standard material thicknesses
• 5/16-inch hex socket drive for use with standard hex keys or Allen drivers
• Grade 316 stainless steel construction for superior corrosion resistance in harsh environments
• Bright, uncoated finish maintains dimensional accuracy at the thread interface

Compatibility

Designed as an OEM-style replacement or standard fastener for mechanical assemblies requiring a 3/8-24 UNF hex socket cap screw in 316 stainless steel.

Installation Notes

Installation is typically performed by licensed mechanics, plumbers, or HVAC technicians using a calibrated hex key or T-handle Allen driver. De-energize and depressurize the equipment before servicing any fastened assembly. Apply appropriate thread lubricant or anti-seize compound when installing stainless fasteners into stainless threaded holes to prevent galling. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
