Value Collection 72184 Hex Socket Cap Screw 3/8-16 Unc 50 Pack

Product Description

The VALUE COLLECTION 72184 is a partially threaded hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies, fixtures, and structural connections. Manufactured from alloy steel with a black oxide coating, this fastener delivers strong corrosion resistance alongside the tensile strength alloy steel is known for. The 3/8-16 UNC thread size and 5/16-inch internal hex drive make it compatible with standard Allen wrenches and hex bit drivers. At 5 inches of length under the head, this screw suits applications requiring deeper thread engagement or thicker material stacks. Sold in a package of 50, it is suitable for shop stock, production runs, or field service kits.

This screw is intended for use in industrial, mechanical, and structural applications where a recessed drive cap screw is required. Partial threading allows for clamping force between mating surfaces without full-thread engagement through the entire fastened stack. Typical installation scenarios include machine frames, jigs and fixtures, equipment enclosures, and maintenance repair operations. This fastener is appropriate for use by millwrights, maintenance technicians, machinists, and mechanical contractors working in both light and heavy industrial environments.

Key Features

• 3/8-16 UNC thread size for broad compatibility with standard tapped holes
• 5-inch length under head for deep-reach fastening applications
• Partially threaded shank allows precise clamping between joined surfaces
• Alloy steel construction provides high tensile strength for demanding applications
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• 5/16-inch hex drive accepts standard Allen wrenches and hex bit sockets
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 fastener standards

Compatibility

Designed as a standard ANSI B18.3-compliant hex socket cap screw suitable for any application requiring a 3/8-16 UNC partially threaded fastener with a 5/16-inch hex drive in alloy steel construction.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen socket driver. Always verify that the receiving hole is tapped to 3/8-16 UNC and is clean and free of debris before driving the fastener. Apply thread-locking compound or lubrication as required by the assembly specification. Torque to the value specified by the equipment manufacturer or applicable engineering standard for 3/8-16 alloy steel fasteners.
