Value Collection KP45141 Hex Head Cap Screw 3/4-16 X 5 in

Product Description

The VALUE COLLECTION KP45141 is a 3/4-16 UNF hex head cap screw measuring 5 inches under the head, manufactured from Grade 8 steel with a zinc-plated finish. This fastener is partially threaded and meets ASTM A354 BD specifications, making it suitable for high-strength bolted connections in mechanical assemblies. Grade 8 steel delivers a tensile strength rating consistent with demanding structural and industrial applications. The zinc plating provides a baseline level of corrosion resistance for general service environments. Licensed mechanics, millwrights, pipefitters, and maintenance technicians working in trade and industrial settings are the typical installers of this fastener.

This screw is used in heavy-duty bolted joint applications where fine-thread engagement and high clamp load are required. The 3/4-16 UNF thread pitch provides greater thread engagement per inch compared to coarse-thread equivalents, which is preferred in applications subject to vibration or where precise torque control is critical. Partial threading allows the unthreaded shank to bear shear loads, a common requirement in structural and mechanical assemblies across industrial, agricultural, and heavy-equipment maintenance work.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high-strength fastener requirements
• 3/4-16 UNF fine thread provides increased thread engagement and vibration resistance
• Partially threaded shank supports shear load bearing in bolted assemblies
• Zinc-plated finish offers baseline corrosion resistance for general service use
• 5-inch length under head accommodates thicker joint stacks and deep grip lengths
• Sold in a package quantity of 10 per order unit

Compatibility

Designed for use with standard 3/4-16 UNF nuts and tapped holes conforming to Unified National Fine thread standards. Suitable for general industrial, mechanical, and structural bolted joint applications requiring a Grade 8 high-strength fastener.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with proper torque specifications for Grade 8 fasteners. Always use a calibrated torque wrench and apply torque values appropriate for the joint material and lubrication condition. Inspect mating threads and bearing surfaces for damage before assembly. Follow applicable ASME or equipment manufacturer specifications for joint design and fastener loading.
