Value Collection KP45112 Hex Cap Screw 5/8-18 X 1-1/2 in Grade 8

Product Description

The VALUE COLLECTION KP45112 is a fully threaded hex head cap screw designed for high-strength mechanical fastening applications. Manufactured from Grade 8 steel with a zinc-plated finish, this screw meets ASTM A354 BD standards, making it suitable for demanding structural and industrial assembly work. The 5/8-18 UNF thread profile provides fine-thread engagement for applications where vibration resistance and precise clamping force are required. Sold in a pack of 25, this fastener is commonly specified by maintenance technicians, mechanical contractors, and industrial assemblers working on equipment that demands certified high-tensile hardware.

This screw is suited for use in industrial machinery, structural steel connections, heavy equipment assembly, and mechanical systems where Grade 8 tensile strength is required. The zinc plating provides basic corrosion resistance for indoor and sheltered outdoor environments. The fully threaded shank allows maximum thread engagement across the full 1-1/2-inch length under the head, offering consistent clamping along the entire fastener length. Packs of 25 are useful for bench stock and service truck inventory.

Key Features

• Grade 8 steel construction meets ASTM A354 BD standard for high-tensile strength fastening
• 5/8-18 UNF fine thread for improved vibration resistance and precise torque control
• Fully threaded along the entire 1-1/2-inch length under head for maximum thread engagement
• Zinc-plated finish provides corrosion resistance in sheltered and indoor environments
• Sold in a pack of 25 units for bench stock or small-quantity service needs

Compatibility

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

Installation Notes

Installation should be performed by a qualified mechanic or mechanical contractor familiar with torque specifications for Grade 8 fasteners. Always verify mating thread condition before installation and use an appropriate hex socket or open-end wrench sized for the 5/8-inch hex head. Do not use impact tools without a verified torque-limiting procedure, as over-torquing can compromise thread integrity. Zinc-plated fasteners are not rated for submersion or highly corrosive environments without additional protective treatment.
