Value Collection 015525BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 015525BR is a hex socket cap screw designed for high-strength fastening in mechanical, structural, and industrial assemblies. It features a 1-8 UNC thread form with a 2-inch length under head and is fully threaded along its entire shank. The 3/4-inch hex drive socket accepts a standard hex key or Allen wrench for installation and removal. Constructed from alloy steel with a black oxide coating, this fastener delivers solid tensile strength and moderate corrosion resistance suitable for indoor and controlled-environment applications. Machinists, millwrights, maintenance technicians, and fabricators install this type of screw across a broad range of equipment and structural builds.

This screw is suited for use in general industrial machinery, jigs, fixtures, tooling plates, and equipment frames where a flush or recessed socket drive is preferred over a hex head. The 1-8 UNC coarse thread pitch is the standard for 1-inch diameter fasteners in inch-based applications and threads reliably into tapped steel, cast iron, and aluminum bores. The black oxide finish reduces light reflection and provides a degree of surface protection when used with appropriate supplemental lubrication or thread-locking compound.

Key Features

• 1-8 UNC coarse thread, 1-inch nominal diameter for high clamping load capacity
• 2-inch length under head, fully threaded for maximum thread engagement
• 3/4-inch hex drive socket for standard Allen key or hex bit driver installation
• Alloy steel construction for elevated tensile and shear strength compared to plain carbon steel
• Black oxide coating reduces surface reflectivity and provides light corrosion inhibition
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as an OEM-style and replacement fastener for industrial machinery, fabrication assemblies, and structural applications requiring a 1-8 UNC socket cap screw with a 2-inch length under head.

Installation Notes

Installation requires a 3/4-inch hex key or socket-style Allen driver; confirm the mating tapped hole meets 1-8 UNC specifications before installation. Inspect threads for contamination or damage prior to assembly and apply thread lubricant or a thread-locking compound as required by the application. Torque to the value specified in the equipment manufacturer's documentation or the applicable ASTM A574 grade minimum. Power down and de-energize or depressurize any assembly before accessing fastener locations on live equipment.
