Value Collection MPKP44163 Hex Cap Screw Grade 8 1-8x2-1/2 5pk

Product Description

The VALUE COLLECTION MPKP44163 is a fully threaded hex head cap screw designed for heavy-duty fastening applications in mechanical assembly, structural connections, and industrial maintenance. Manufactured from Grade 8 steel with a zinc-plated finish, this fastener meets ASTM A354 BD standards for high tensile strength and corrosion resistance. The 1-8 UNC thread form and 2-1/2-inch length under head make it suitable for thick-section clamping and through-bolt configurations. Sold in a package of 5, this screw is a practical addition to a working hardware inventory for contractors, millwrights, and maintenance technicians who need a reliable Grade 8 fastener on hand.

This hex head cap screw is used across a wide range of trade applications including HVAC equipment mounting, pump and motor assembly, structural steel connections, and general mechanical maintenance. The fully threaded shank provides maximum thread engagement throughout the grip length, which is particularly useful in applications where a nut and washer are used without a tapped hole. The UNC thread standard ensures broad compatibility with standard hex nuts, lock nuts, and threaded inserts commonly stocked in trade shops and service vans.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high tensile and proof load requirements

Compatibility

Designed for use with standard 1-8 UNC hex nuts, flat washers, lock washers, and threaded inserts. Compatible with through-hole and tapped applications requiring a Grade 8 fastener per ASTM A354 BD specifications.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or trade technician familiar with proper fastener torque procedures for Grade 8 hardware. Always confirm hole clearance, thread condition, and mating hardware grade before assembly. Use the appropriate hex wrench or socket to achieve proper seating without overdriving. Inspect the zinc-plated finish for damage prior to installation in corrosive or outdoor environments where additional corrosion protection may be required.
