Value Collection 581854BR Hex Socket Cap Screw 1-14 Unf

Product Description

The VALUE COLLECTION 581854BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and industrial equipment. It features a 1-14 UNF thread size, a 7-inch length under the head, and a 3/4-inch hex drive socket for installation with a standard hex key or Allen wrench. Manufactured from alloy steel with a black oxide finish, this screw offers good hardness and corrosion resistance for use in controlled shop and facility environments. It meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards.

This socket cap screw is suited for applications that require a recessed drive fastener with a fine-thread profile. The 1-14 UNF thread pitch provides tighter thread engagement than coarse-thread equivalents, making it appropriate for high-load or vibration-prone assemblies. Typical installations include machine bases, fixtures, jigs, hydraulic components, and structural fabrication work where precision fit and clamping force are critical. Licensed machinists, millwrights, and mechanical contractors are the primary installers of this fastener.

Key Features

• 1-14 UNF fine-thread profile for high clamping force and vibration resistance
• 7-inch length under head accommodates deep or stacked material assemblies
• 3/4-inch hex socket drive for use with standard Allen keys or hex bit sockets
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide finish provides mild corrosion protection and reduces light glare on finished assemblies
• Partially threaded shank for shoulder bearing and precise positional alignment

Compatibility

Designed as an OEM-style replacement or direct-use fastener for applications requiring a 1-14 UNF partially threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Always de-energize and lock out equipment before replacing or installing fasteners in mechanical assemblies. Use a properly sized 3/4-inch hex key or Allen bit socket to avoid rounding the drive recess. Torque to the value specified by the equipment manufacturer or applicable industry standard for the thread size and material class. Inspect the mating threaded hole for damage or contamination before installation.
