Value Collection KP45114 5/8-18x2 Grade 8 Hex Cap Screw 25pk

Product Description

The VALUE COLLECTION KP45114 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 fastener meets ASTM A354 BD standards, making it suitable for demanding load-bearing connections. The 5/8-18 UNF thread profile provides fine-thread engagement for applications requiring precise torque control and strong clamp force. Sold in a package of 25, the KP45114 is appropriate for shops, contractors, and maintenance teams that need consistent, specification-compliant hardware on hand.

This screw is used in mechanical assemblies, equipment mounting, and structural connections where fine-thread fasteners are specified. The 5/8-18 thread size and 2-inch length under head make it a common fit for machinery frames, brackets, flanges, and fabricated steel components. Grade 8 classification indicates a minimum tensile strength appropriate for heavy-duty bolted joints. Tradespeople in HVAC, plumbing, and general mechanical service regularly use Grade 8 fasteners when manufacturer specifications or structural requirements call for high-strength hardware.

Key Features

• Grade 8 steel construction meets ASTM A354 BD standard for high-strength bolted connections
• 5/8-18 UNF fine-thread profile for precise torque control and secure clamp load
• Fully threaded along the 2-inch length under head for maximum thread engagement
• Zinc-plated finish provides basic corrosion resistance in dry indoor environments
• Package quantity of 25 supports job-lot purchasing with a minimum order of 1 package

Compatibility

Designed as a standard UNF hex head cap screw for use in any application specifying a 5/8-18 x 2-inch Grade 8 fully threaded fastener per ASTM A354 BD.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with fastener torque requirements for Grade 8 hardware. Always verify that the mating nut or tapped hole is rated for the same thread class and strength grade before assembly. Use calibrated torque tools and follow the joint designer or equipment manufacturer torque specifications. Inspect the zinc-plated finish for damage before installation, as surface nicks can reduce corrosion resistance in exposed environments.
