Value Collection 581963BR Hex Socket Cap Screw 1-1/2-12 Unf

Product Description

The VALUE COLLECTION 581963BR is a hex socket cap screw designed for high-strength fastening applications where a flush or recessed drive is required. Machined from alloy steel and finished with a black oxide coating, this fastener offers improved corrosion resistance in moderate environments. The 1-inch hex drive accepts a standard Allen-style key or socket, and the fully threaded 3-inch body under head engages the full grip length of the joint. With a thread size of 1-1/2-12 UNF, it provides fine-pitch thread engagement suited to precision assemblies, heavy equipment, and high-load connections. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for mechanical and structural trade applications.

This fastener is suited for use in industrial, mechanical, and commercial maintenance environments where fine-pitch, large-diameter socket cap screws are specified. Typical applications include heavy machinery assembly, tooling fixtures, hydraulic and pneumatic component mounting, and structural connections requiring controlled torque and positive drive engagement. The black oxide finish reduces friction during installation and provides light corrosion protection in dry or lightly oiled conditions.

Key Features

• 1-1/2-12 UNF thread size provides fine-pitch engagement for high-load, precision fastening
• Fully threaded 3-inch length under head maximizes thread engagement across the grip
• 1-inch hex socket drive compatible with standard Allen keys and socket tools
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion resistance and reduced galling during installation
• Meets ASME/ANSI B18.3 dimensional standards for socket head cap screws

Compatibility

Designed as an OEM-style and general-purpose replacement socket cap screw for applications specifying 1-1/2-12 UNF fully threaded fasteners per ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation of large-diameter socket cap screws should be performed by a qualified mechanical or maintenance technician using a calibrated torque wrench and the appropriately sized 1-inch hex key or socket driver. Always verify thread compatibility and joint material before installation. Ensure mating threads are clean and free of debris, and apply thread lubricant or anti-seize compound as required by the assembly specification. Do not exceed the torque values specified by the equipment manufacturer or applicable industry standards.
