Value Collection 015533BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 015533BR is a hex socket cap screw designed for high-strength fastening in industrial, mechanical, and structural applications. It features a 1-8 UNC thread size with a 3-inch length under head and is fully threaded from tip to head. The screw is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection. The 3/4-inch hex drive requires a matching hex key or Allen driver. This fastener is installed by machinists, maintenance technicians, millwrights, and mechanical assemblers working across general manufacturing and equipment fabrication.

This screw is suited for medium-to-heavy-duty bolted assemblies where a recessed drive head is required to sit flush or below the surface of the mating component. Common applications include machine tool fixtures, jigs, hydraulic component mounting, and structural mechanical assemblies. The fully threaded configuration provides maximum thread engagement across the entire shank length, making it appropriate for through-hole and shorter-grip fastening scenarios where full clamp load is needed.

Key Features

• 1-8 UNC thread size for broad compatibility with standard inch-series tapped holes
• 3-inch length under head with full threading for maximum thread engagement
• Alloy steel construction provides high tensile strength per ASTM A574
• Black oxide finish offers mild corrosion resistance and low-glare appearance
• 3/4-inch hex drive size accepts standard hex keys and socket drivers
• 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 application requiring a 1-8 UNC tapped hole with a 3-inch grip length.

Installation Notes

Installation requires a properly sized 3/4-inch hex key or T-handle Allen driver. Ensure the mating tapped hole meets 1-8 UNC thread specifications before installation. Clean threads and inspect for damage prior to assembly. Follow applicable torque specifications from a recognized fastener reference such as the IFI Fastener Standards or the equipment manufacturer's service documentation.
