Value Collection 7556BHT Hex Cap Screw 3/4-10 X 3-1/2 in Grade 2

Product Description

The VALUE COLLECTION 7556BHT is a fully threaded hex head cap screw designed for general-purpose fastening in mechanical, structural, and equipment-assembly applications. It is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in low-exposure environments. The screw features a 3/4-10 UNC thread and measures 3-1/2 inches under the head, conforming to ASME B18.2.1, ASTM A307, and SAE J429 standards. Electricians, plumbers, HVAC technicians, and general tradespeople use this fastener when securing brackets, equipment supports, and mechanical assemblies that call for a standard-grade hex cap screw.

This fastener suits a wide range of light to medium-duty applications where high-strength or alloy-grade hardware is not required. Typical installations include equipment mounting, structural framing connections, and fixture support in residential and light commercial construction. The 3/4-10 UNC thread is one of the most common coarse-thread sizes in trade work, making this screw compatible with standard nuts, threaded rod couplings, and tapped holes machined to UNC specifications.

Key Features

• 3/4-10 UNC coarse thread for broad compatibility with standard nuts and tapped holes
• Fully threaded along the 3-1/2 inch under-head length for maximum thread engagement
• Grade 2 steel construction meets ASTM A307 and SAE J429 requirements
• Zinc-plated finish provides basic corrosion protection in dry to mildly humid conditions
• Conforms to ASME B18.2.1 dimensional standards for consistent hex head geometry

Compatibility

Designed as a standard-grade hex head cap screw for use with 3/4-10 UNC nuts, flat washers, lock washers, and threaded rod couplings in general mechanical and structural fastening applications.

Installation Notes

Install using a properly sized hex socket or open-end wrench rated for the fastener size. Power down and de-energize any equipment before fastening in electrical or HVAC enclosures. Do not substitute this Grade 2 fastener in applications that specify Grade 5, Grade 8, or other higher-strength hardware. Follow applicable building and mechanical codes for torque and joint requirements.
