Value Collection 88547294 Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 88547294 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, structural connections, and industrial equipment. It features a 1-8 UNC thread size with a 4-inch length under the head and accepts a 3/4-inch hex drive. The fastener is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces surface glare. This screw is partially threaded, which allows it to clamp two workpieces together without threading into the full shaft length. Maintenance technicians, millwrights, and industrial mechanics commonly install this type of fastener.

This hex socket cap screw is suited for use in machinery frames, jigs, fixtures, and fabricated steel assemblies where a recessed drive head is required for flush or low-profile installation. The partially threaded design makes it appropriate for bolted joints where a smooth shank section is needed between clamped materials. It is a standard inch-series cap screw widely used in manufacturing, repair, and industrial maintenance environments.

Key Features

• 1-8 UNC thread form for strong engagement in steel and iron tapped holes
• 4-inch length under head accommodates deeper clamping applications
• 3/4-inch hex socket drive for use with standard hex keys and socket drivers
• Partially threaded shank reduces stress concentration and supports clamping load
• Alloy steel construction provides high tensile strength for demanding fastening applications
• Black oxide finish offers mild corrosion protection and a non-reflective surface

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any tapped hole or nut accepting a 1-8 UNC thread, common in industrial machinery, fabrication assemblies, and maintenance repair applications.

Installation Notes

Installation is performed by millwrights, maintenance mechanics, or other qualified tradespeople using a 3/4-inch hex key or socket driver. Ensure the mating tapped hole or nut matches the 1-8 UNC thread specification before installation. Power down and de-energize any equipment before accessing fastener locations in live machinery. Do not use impact drivers at high torque settings without confirming fastener grade and joint design requirements.
