Value Collection 011585BR Hex Socket Cap Screw 1-1/2-6 Unc

Product Description

The VALUE COLLECTION 011585BR is a hex socket cap screw designed for high-strength bolted connections in industrial, mechanical, and structural assemblies. Sized at 1-1/2-6 UNC with a 3-1/2 inch length under head, this fastener is fully threaded and driven with a 1-inch hex (Allen) key. The alloy steel construction is finished with a black oxide coating, which provides mild corrosion resistance and reduces light reflection in service environments. This screw meets ASME/ANSI B18.3 dimensional standards and ASTM A574 mechanical property requirements, making it suitable for demanding load-bearing applications where a recessed drive is preferred over an external hex head.

This socket cap screw is used in general industrial machinery, tooling fixtures, hydraulic and pneumatic assemblies, and heavy equipment where controlled clamping force and a low-profile head are needed. The coarse UNC thread pitch is appropriate for use in softer base materials or in applications requiring faster engagement during assembly. Licensed machinists, millwrights, pipefitters, and mechanical contractors are the typical installers for fasteners in this size range.

Key Features

• Thread size 1-1/2-6 UNC with fully threaded body for maximum engagement throughout the shank
• 3-1/2 inch length under head accommodates thicker material stacks or deep through-holes
• 1-inch hex drive size requires a standard ANSI hex key or socket for installation
• Alloy steel construction provides high tensile strength suitable for load-bearing connections
• Black oxide finish offers mild corrosion resistance and a non-reflective surface
• Meets ASME/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance

Compatibility

Designed as a standard replacement or new-installation socket cap screw for any application requiring a 1-1/2-6 UNC fully threaded fastener with a 1-inch hex drive and 3-1/2 inch length under head, per ASME/ANSI B18.3 specification.

Installation Notes

Installation of large-diameter socket cap screws in this size range typically requires a calibrated torque wrench to achieve proper clamping load without yielding the fastener. De-energize or depressurize any equipment before accessing fastened joints. Follow ASME or equipment-manufacturer torque specifications appropriate to the grade and thread engagement for this fastener class. Inspect threaded holes for damage or debris before driving the screw to avoid galling the alloy steel threads.
