Value Collection 011545P Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 011545P is a hex socket cap screw engineered for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural components. Sized at 1-8 UNC thread with a 5-1/2 inch length under head, this partially threaded fastener uses a 3/4 inch hex drive and is manufactured from alloy steel with a black oxide finish for corrosion resistance and reduced surface reflectivity. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding load-bearing connections where a standard hardware-grade fastener would not suffice. Machinists, maintenance technicians, and industrial mechanics are the typical installers.

This screw is appropriate for use in heavy machinery, tooling fixtures, hydraulic equipment mounts, and general industrial fabrication where a coarse 1-8 UNC thread engagement and a partially threaded shank are required. The black oxide coating suits indoor and lightly protected environments. It is sold individually and is compatible with any 3/4 inch hex key or drive tool.

Key Features

• 1-8 UNC coarse thread for strong engagement in steel and iron components
• 5-1/2 inch length under head with partial threading for shank clearance applications
• 3/4 inch hex socket drive for high-torque installation
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish reduces reflectivity and provides mild corrosion resistance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 1-8 UNC partially threaded fastener with a 3/4 inch hex drive.

Installation Notes

Installation requires a 3/4 inch hex key or socket drive rated for the torque demands of an ASTM A574 alloy steel cap screw. Ensure mating threads in the receiving component are clean and free of debris before installation. Do not install in applications exposed to sustained moisture or corrosive environments without additional protective coating. Follow applicable machinery or structural specifications for proper seating torque.
