Value Collection 581703BR Hex Socket Cap Screw 1-12 Unf

Product Description

The VALUE COLLECTION 581703BR is a partially threaded hex socket cap screw designed for high-strength bolted assemblies in industrial, mechanical, and structural applications. It features a 1-12 UNF thread and a 6-inch length under the head, providing substantial clamping depth for thick material stacks. The 3/4-inch hex drive requires a matching hex key or Allen driver. Constructed from alloy steel with a black oxide finish, this fastener offers solid corrosion resistance and wear durability in demanding service environments. It is commonly installed by millwrights, maintenance mechanics, and field technicians working on machinery, tooling fixtures, and fabricated assemblies.

This screw is suited for applications requiring fine-pitch UNF threading where vibration resistance and precise torque control matter. The 1-12 UNF designation makes it appropriate for moderately heavy fastening tasks where a fine thread engagement is preferred over coarse-thread alternatives. The black oxide coating reduces galling during installation and provides light surface protection in indoor or sheltered installations. Typical use cases include machine bases, press frames, die fixtures, and similar industrial assemblies where alloy steel strength grades are specified.

Key Features

• 1-12 UNF partially threaded shank for fine-pitch fastening with strong thread engagement
• 6-inch length under head accommodates thick material stacks and deep clearance holes
• 3/4-inch hex socket drive for high-torque installation with standard hex keys
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish reduces galling and provides light corrosion resistance

Compatibility

Designed as an OEM-style or aftermarket replacement hex socket cap screw for industrial machinery, fabricated fixtures, and structural assemblies requiring 1-12 UNF alloy steel fasteners conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is typically performed by qualified mechanics or millwrights using a calibrated torque wrench and a 3/4-inch hex key or Allen socket. Ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from the equipment manufacturer or referenced engineering standards. Do not exceed the rated torque for the thread size and material grade to avoid fastener damage or joint failure.
