Value Collection 403184PS Hex Head Cap Screw 1/2-13 X 1.5 in

Product Description

The VALUE COLLECTION 403184PS is a fully threaded hex head cap screw designed for general-purpose fastening in structural and mechanical assemblies. It is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in indoor and light-duty environments. The fastener measures 1/2-13 thread size by 1.5 inches under the head and conforms to ASME B18.2.1, ASTM A307, and SAE J429 standards. It uses a UNC (Unified National Coarse) thread form and requires a 0.75-inch hex key or wrench for installation. This screw is a standard trade-supply fastener used by millwrights, pipefitters, HVAC technicians, and general contractors.

This screw is suited for residential and light commercial construction, mechanical equipment mounting, and general structural assembly. Its fully threaded body makes it appropriate for applications where thread engagement along the full length of the fastener is required, such as short-grip bolting situations or through-bolt assemblies with a nut. Compatible with standard 1/2-13 UNC hex nuts, flat washers, and lock washers available in most trade fastener inventories.

Key Features

• Fully threaded body provides maximum thread engagement along the entire shank length
• Grade 2 steel construction meets ASTM A307 and SAE J429 standards for general-purpose applications
• Zinc-plated finish offers basic corrosion protection for indoor and sheltered installations
• UNC thread form ensures broad compatibility with standard 1/2-13 hardware
• Conforms to ASME B18.2.1 dimensional standards for consistent fit across tooling and fastener systems
• 0.75-inch hex drive accepts standard open-end, box-end, and socket wrenches

Compatibility

Designed as a standard 1/2-13 UNC fully threaded hex head cap screw for use with compatible 1/2-13 nuts, threaded inserts, and tapped holes in general mechanical and structural applications.

Installation Notes

Installation is performed with a 0.75-inch open-end, box-end, or socket wrench. De-energize and lock out any equipment before fastening components on live machinery per applicable OSHA lockout-tagout procedures. Follow applicable torque specifications from the equipment manufacturer or relevant codes such as AISC or ASME standards for the specific joint type. Avoid overtightening, which can strip the Grade 2 threads or induce fastener fatigue in lower-strength applications.
