Value Collection KP44113 Hex Cap Screw 5/8-11 Grade 8 Zinc 25pk

Product Description

The VALUE COLLECTION KP44113 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel with a zinc-plated finish, this 5/8-11 UNC screw measures 1-3/4 inches under the head and meets ASTM A354 BD standards for tensile and proof load requirements. The zinc plating provides a base level of corrosion resistance suitable for indoor and sheltered environments. Each package contains 25 screws, making it a practical quantity for both service calls and shop inventory.

This fastener is used across a wide range of trade applications including HVAC equipment mounting, mechanical equipment bases, structural steel connections, and general industrial assembly. The 5/8-11 UNC thread is a common coarse-thread standard found in machinery, frames, flanges, and equipment enclosures. Grade 8 classification makes it appropriate where elevated tensile strength is required compared to Grade 2 or Grade 5 fasteners. It is typically installed by millwrights, pipefitters, HVAC mechanics, and general maintenance technicians.

Key Features

• Grade 8 steel construction meets ASTM A354 BD tensile and proof load requirements
• Fully threaded along the 1-3/4 inch shank length for maximum thread engagement
• 5/8-11 UNC coarse thread standard for broad hardware compatibility
• Zinc-plated finish provides basic corrosion protection in sheltered installations
• Sold in a 25-piece package suitable for stocking or single-job use

Compatibility

Designed as a standard 5/8-11 UNC hex head cap screw compatible with any application requiring a Grade 8 fully threaded fastener of this thread size and length under head.

Installation Notes

Installation requires an appropriate hex socket or open-end wrench sized for a 5/8-11 fastener. Always verify mating thread condition and clean threads before installation to ensure proper torque takeup. Power down or de-energize any equipment before performing fastener work on electrical enclosures or mechanical assemblies. Follow applicable mechanical or structural codes for torque requirements based on joint type and application.
