Value Collection 011553BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 011553BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 1-8 UNC thread size with 8 inches of length under the head and accepts a 3/4-inch hex drive for installation with a hex key or Allen wrench. Constructed from alloy steel with a black oxide finish coating, this fastener delivers solid tensile strength and moderate corrosion resistance. The partial threading design ensures proper clamping force when drawing two members together. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it a recognized choice for demanding fastening work.

This screw is suited for use in machinery, tooling fixtures, heavy equipment, and fabricated steel assemblies where a flush or low-profile socket-drive fastener is required. The 1-8 UNC coarse thread pitch makes it well suited for steel and iron substrates where quick engagement and thread strength are priorities. Machinists, millwrights, maintenance technicians, and fabricators commonly install this type of fastener in both production and field service settings.

Key Features

• 1-8 UNC coarse thread for reliable engagement in steel and iron
• 8-inch length under head accommodates thick stack-ups and deep clearance holes
• 3/4-inch hex socket drive for use with standard hex keys or T-handle wrenches
• Alloy steel construction for high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and reduces light glare
• Partially threaded shank maintains clamping integrity across unthreaded grip length
• Meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards

Compatibility

Designed as a standard 1-8 UNC hex socket cap screw for use in tapped holes or with appropriate nuts in industrial and mechanical assemblies requiring ASME/ANSI B18.3 and ASTM A574 compliant fasteners.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 3/4-inch hex key or appropriately rated torque wrench. Ensure the receiving tapped hole or nut is clean and free of debris before driving the screw. Follow applicable industry torque guidelines for ASTM A574 alloy steel socket cap screws at the specified thread size. Black oxide finish offers limited corrosion protection, so apply a thread lubricant or anti-seize compound in wet or outdoor environments as appropriate.
