Value Collection 581964BR Hex Socket Cap Screw 1-1/2-12 Unf

Product Description

The VALUE COLLECTION 581964BR is a hex socket cap screw designed for high-strength fastening applications. It features a 1-1/2-12 UNF thread, a 3.5-inch length under head, and is fully threaded from bearing surface to tip. Manufactured from alloy steel with a black oxide finish, this fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding mechanical assemblies where tensile strength and dimensional consistency are critical. A 1-inch hex drive socket is required for installation. This type of fastener is commonly used by industrial maintenance technicians, millwrights, and mechanical contractors working on machinery, tooling, and structural steel assemblies.

This socket cap screw is suited for applications requiring a fine-thread fastener in high-load or vibration-prone environments. The 1-1/2-12 UNF thread pitch provides greater thread engagement per inch compared to coarse-thread equivalents, making it a preferred choice for precision assemblies, heavy equipment, hydraulic manifolds, and close-tolerance mechanical joints. It is appropriate for both new installations and maintenance replacement work in industrial and commercial settings.

Key Features

• 1-1/2-12 UNF fine thread for high-load and vibration-resistant applications
• 3.5-inch length under head, fully threaded
• Alloy steel construction per ASTM A574 for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• 1-inch hex drive socket interface per ASME/ANSI B18.3
• Conforms to UNSPSC Code 31161501

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 1-1/2-12 UNF fully threaded fastener with a 1-inch hex drive socket interface.

Installation Notes

Installation should be performed by a qualified millwright, maintenance technician, or mechanical contractor using a calibrated 1-inch hex socket driver or Allen-type key. Always degrease and inspect threaded holes before installation to ensure proper thread engagement. Do not cross-thread or over-drive; apply thread lubricant or anti-seize as required by the assembly specification. Follow all applicable industry torque standards and equipment manufacturer guidelines for the specific assembly.
