Value Collection 011533P Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 011533P is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural connections. It features a 1-8 UNC thread and a 3-inch length under head, with full threading along the entire shank. The 3/4-inch hex drive accepts a standard hex key or Allen wrench. Constructed from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance in moderate environments and meets ASME/ANSI B18.3 and ASTM A574 standards. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in production and repair work.

This socket cap screw is suited for applications where a recessed drive is required to clear surrounding material or where a low-profile head is needed. Common install scenarios include machine frames, fixture plates, jig components, and general industrial assemblies. The fully threaded design provides consistent thread engagement across the full 3-inch length, making it useful in through-hole and tapped-hole applications alike. This screw is sold individually.

Key Features

• 1-8 UNC thread for use with standard inch-series tapped holes in that size
• 3-inch length under head, fully threaded for maximum thread engagement
• 3/4-inch hex socket drive accepts standard hex keys or Allen drivers
• Alloy steel construction meets ASTM A574 for high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style and aftermarket replacement hex socket cap screw for 1-8 UNC tapped holes in industrial machinery, fixtures, and structural assemblies requiring ASME/ANSI B18.3 and ASTM A574 compliant fasteners.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 3/4-inch hex key or T-handle driver. Ensure the mating tapped hole is clean and free of debris before threading in the fastener. Torque to the value specified by the assembly drawing or applicable engineering standard for the fastener grade and size. Do not exceed the rated thread engagement depth of the receiving material.
