Value Collection 015281PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 015281PR is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and equipment fabrication. It features a 3/8-16 UNC thread size with a 5-inch length under head, driven by a 5/16-inch hex socket. The screw is manufactured from alloy steel with a black oxide finish, which provides moderate corrosion resistance and reduces light reflection in finished assemblies. This fastener meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it suitable for demanding industrial and mechanical installations requiring reliable clamping force.

This cap screw is used across a wide range of industrial, mechanical, and maintenance applications including machine frames, fixtures, jigs, HVAC equipment mounting, electrical enclosures, and general structural assemblies. The alloy steel construction and black oxide coating make it a common choice in environments where moderate corrosion resistance and high tensile strength are both priorities. It is appropriate for use by millwrights, machinists, maintenance technicians, and trade professionals requiring a standardized high-strength fastener.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard inch-series tapped holes
• 5-inch length under head provides deep engagement for thick-section assemblies
• Partially threaded shank allows for precise shear and shoulder loading
• Alloy steel construction meets ASTM A574 high-strength cap screw requirements
• Black oxide finish reduces surface corrosion and minimizes light reflection
• 5/16-inch hex drive accepts standard hex keys and socket drivers

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any 3/8-16 UNC tapped hole requiring a partially threaded fastener with a 5-inch grip length.

Installation Notes

Installation requires a 5/16-inch hex key or socket driver. Verify the receiving hole is clean, properly tapped to 3/8-16 UNC, and free of debris before installation. Apply thread lubricant or thread-locking compound as specified by the equipment manufacturer or applicable fastener standard. De-energize and lock out any equipment before replacing or installing fasteners on live machinery.
