Value Collection -33711-1 Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION -33711-1 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 1-8 UNC thread size and a 2-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 coating, this fastener offers solid tensile strength and moderate corrosion resistance in indoor and controlled environments. It is a common choice for maintenance technicians, machinists, and mechanical contractors who need a reliable, specification-grade socket head cap screw.

This screw is suited for use in mechanical assemblies requiring precise clamping force and a recessed drive head. Fully threaded construction makes it appropriate for through-hole applications and shorter clamped-length joints. The 1-8 UNC coarse thread pitch is widely used in general industrial and commercial fastening where quick assembly and strong thread engagement are priorities. Typical installation scenarios include machine bases, brackets, jigs, and structural mechanical joints where a flush or low-profile head is required.

Key Features

• 1-8 UNC coarse thread for broad compatibility with standard tapped holes
• 2-inch length under head with full threading along the entire shank
• 3/4-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction for high tensile and yield strength
• Black oxide coating provides mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as a standard ASME/ANSI B18.3 and ASTM A574 compliant hex socket cap screw for use in any application requiring a 1-8 UNC tapped hole with a 2-inch fastener length.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical technicians using a calibrated torque wrench and the appropriate 3/4-inch hex key or bit. Ensure the mating tapped hole is clean, free of debris, and threaded to the correct UNC specification before driving the fastener. Apply thread lubricant or anti-seize compound as appropriate for the joint material and service conditions. Do not exceed the recommended torque for the fastener grade and thread size as specified in ASME B18.3 reference tables.
