Value Collection KP44133 3/4-10 X 2-1/2 in Grade 8 Hex Cap Screw 25pk

Product Description

The VALUE COLLECTION KP44133 is a fully threaded hex head cap screw sized 3/4-10 UNC by 2-1/2 inches under the head. Made from Grade 8 steel with a zinc-plated finish, this fastener meets ASTM A354 BD standards, making it suitable for high-strength structural and mechanical bolting applications. The coarse 3/4-10 UNC thread profile allows for fast engagement in standard tapped holes and threaded inserts. Grade 8 steel provides significantly higher tensile and proof load ratings than Grade 5 or Grade 2 equivalents, which is why it is the go-to choice for critical joint applications in heavy equipment, structural assemblies, and industrial machinery. Licensed trades and general contractors specify this grade when fastener failure is not an option.

This cap screw is used across a wide range of industrial and construction applications including structural steel connections, heavy equipment mounting, conveyor and machinery frames, and mechanical assemblies that require a high-strength bolted joint. The zinc plating provides a baseline level of corrosion resistance suitable for dry indoor environments and light outdoor exposure. It is sold in a package of 25 pieces, which suits both bench stock replenishment and single-job use. Typical installers include millwrights, ironworkers, pipefitters, and general contractors working on structural or equipment-mounting tasks.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high-strength bolting requirements
• Fully threaded shank along the 2-1/2 inch under-head length for maximum thread engagement
• 3/4-10 UNC coarse thread standard for compatibility with standard tapped holes and nuts
• Zinc-plated finish provides baseline corrosion protection for general service environments
• Package quantity of 25 pieces supports both stock replenishment and single-task use

Compatibility

Designed as a standard 3/4-10 UNC hex head cap screw compatible with any tapped hole, hex nut, or threaded insert machined to ASME B1.1 coarse thread specification at the 3/4 inch nominal diameter.

Installation Notes

Installation is typically performed by millwrights, ironworkers, or maintenance mechanics using a standard 1-1/8 inch hex wrench or impact socket. Always confirm mating thread class and tapped hole depth before installation to ensure full thread engagement. Torque to joint-specific engineering requirements per applicable structural or equipment specifications. Do not mix Grade 8 fasteners with lower-grade nuts or washers in load-bearing assemblies.
