Value Collection 581852BR Hex Socket Cap Screw 1-14 Unf

Product Description

The VALUE COLLECTION 581852BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at 1-14 UNF with a 6-inch length under head, it accepts a 3/4-inch hex drive for positive torque transfer. Constructed from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and surface hardness suited to demanding service environments. It meets ASME/ANSI B18.3 and ASTM A574 standards, confirming dimensional accuracy and tensile strength appropriate for critical joints. Machinists, maintenance mechanics, and industrial assemblers commonly specify this style of cap screw for precision equipment and heavy-duty fixtures.

This screw is suited for applications requiring a flush or recessed head profile with high clamping force. The 1-14 UNF thread form provides finer thread pitch than coarse-series equivalents, making it a common choice where vibration resistance or precise preload control is required. Partial threading allows for clearance-hole grip in multi-piece assemblies. Typical installations include machine frames, hydraulic manifolds, industrial tooling, and structural mechanical joints where a hex-drive fastener is specified.

Key Features

• 1-14 UNF thread for fine-pitch engagement and vibration resistance
• 6-inch length under head accommodates deep-reach fastening applications
• 3/4-inch hex socket drive for high-torque installation with standard Allen or hex-key tooling
• Partially threaded shank provides grip length for clearance-hole assemblies
• Alloy steel construction meets ASTM A574 tensile strength requirements
• Black oxide coating adds corrosion resistance and reduces surface galling

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application calling for a 1-14 UNF partially threaded socket head cap screw in alloy steel.

Installation Notes

Installation should be performed by a qualified mechanic or industrial assembler using a calibrated 3/4-inch hex key or socket drive tool. De-energize, depressurize, or lock out the equipment assembly before installing or removing fasteners in live systems. Verify that mating threads are clean and free of damage before seating the screw. Do not substitute this fastener in applications specifying a different thread standard or grade without confirming equivalency.
