Value Collection D30160-4 Hex Head Cap Screw 3/4-10 X 4 in

Product Description

The VALUE COLLECTION D30160-4 is a 3/4-10 UNC hex head cap screw measuring 4 inches under the head, manufactured from Grade 5 steel with a zinc-plated finish. This partially threaded fastener meets ASME B18.2.1 dimensional standards, making it a reliable choice for structural and mechanical assembly applications. The zinc coating provides basic corrosion resistance in moderate-exposure environments. Maintenance technicians, millwrights, and general contractors reach for this screw when a strong, standardized hex fastener is required in steel-to-steel or steel-to-plate connections.

This fastener is suited for use in mechanical equipment assembly, frame fabrication, HVAC equipment mounting, electrical panel support structures, and general industrial maintenance. The 3/4-10 thread size and 4-inch length under the head make it appropriate for medium-to-heavy-duty bolted connections where Grade 5 tensile strength is specified. The partial threading allows for a smooth shank bearing surface in clearance holes, which is common in structural joint applications.

Key Features

• 3/4-10 UNC thread size with 4-inch length under head
• Grade 5 steel construction for medium-to-heavy-duty tensile load requirements
• Zinc-plated finish for basic corrosion resistance
• Partially threaded shank provides a smooth bearing surface in clearance holes
• Meets ASME B18.2.1 dimensional standards for hex head cap screws

Compatibility

Designed as a standard 3/4-10 UNC hex head cap screw for use in any application requiring an ASME B18.2.1-compliant Grade 5 fastener with a 4-inch length under the head.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or general contractors using a standard 1-1/8-inch hex wrench or impact socket. Verify that the mating nut or tapped hole is also rated for 3/4-10 UNC thread engagement before assembly. Apply a hardened flat washer under the head and at the nut to distribute clamping load and protect the workpiece surface. Do not exceed the rated tensile strength of Grade 5 fasteners by using impact tools at maximum torque without a calibrated torque wrench for final verification.
