Value Collection 015255PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 015255PR is a hex socket cap screw designed for secure, high-load fastening in mechanical and structural assemblies. It features a 3/8-16 UNC thread size with 1 inch of length under the head and is fully threaded along its entire shaft. The 5/16 inch hex drive socket accepts a standard hex key or Allen wrench for installation and removal. Constructed from alloy steel with a black oxide finish, this fastener offers improved corrosion resistance and reduced light reflection compared to uncoated steel. It is suited for maintenance, fabrication, and OEM assembly applications across industrial and trade settings.

This cap screw is commonly used in machinery, equipment frames, jigs, fixtures, and general mechanical assemblies where a recessed drive fastener is preferred over a hex head bolt. The fully threaded design provides consistent thread engagement throughout the clamping length, making it appropriate for shorter through-bolt and tapped-hole installations. Machinists, millwrights, and maintenance technicians regularly use this fastener type in both shop and field settings.

Key Features

• 3/8-16 UNC thread for wide compatibility with standard inch-series tapped holes
• Fully threaded shaft maximizes thread engagement in short-reach applications
• 5/16 inch hex socket drive for use with standard Allen keys and hex drivers
• Alloy steel construction provides high tensile strength and shear resistance
• Black oxide finish reduces surface corrosion and minimizes glare
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any 3/8-16 UNC tapped hole or compatible threaded assembly where a 1 inch length under head and fully threaded profile are specified.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 5/16 inch hex key or a hex bit driver. Always de-energize or lockout-tagout equipment before replacing fasteners in powered assemblies. Do not exceed the rated torque for the alloy steel grade and thread size per applicable engineering references. Inspect mating threads for damage or contamination before installation to ensure full thread engagement.
