Value Collection 99180 Hex Head Cap Screw 3/4-10x4 Grade 8

Product Description

The VALUE COLLECTION 99180 is a 3/4-10 x 4 inch hex head cap screw manufactured from Grade 8 steel with an uncoated finish. This fastener features partial threading and conforms to ASME B18.2.1 standards, making it appropriate for high-strength structural and mechanical assembly applications. The 3/4-10 designation indicates a 3/4-inch nominal diameter with 10 threads per inch on a Unified National Coarse (UNC) thread form. Grade 8 steel provides significantly higher tensile and proof load ratings than Grade 5 or Grade 2 fasteners. Sold in a package quantity of 25, this screw is used by maintenance technicians, millwrights, and general contractors in industrial and commercial settings.

This fastener is suited for heavy-duty bolted connections where high clamping force is required. Typical applications include equipment mounting, structural steel assembly, machinery repair, and industrial fabrication. The partially threaded shank provides a smooth bearing surface in the grip zone, which is preferred in applications where shear load is a factor. The uncoated steel finish is appropriate for dry or controlled environments and for applications where a specific coating will be applied after assembly.

Key Features

• Grade 8 steel construction for high tensile strength in demanding bolted joints
• 3/4-10 UNC thread form for broad compatibility with standard hex nuts and tapped holes
• Partially threaded shank provides a smooth grip zone suitable for shear-loaded connections
• Conforms to ASME B18.2.1 dimensional standards for consistent fit and interchangeability
• Uncoated finish allows for post-assembly coating or use in controlled environments
• Packaged in quantities of 25 for multi-fastener jobs and inventory stocking

Compatibility

Designed for use with standard 3/4-10 UNC hex nuts, flat washers, and lock washers in bolted assemblies conforming to inch-series fastener specifications.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with proper fastener torque practices for Grade 8 hardware. Always use a calibrated torque wrench and refer to the applicable engineering specification or fastener torque table for the required clamp load. Ensure mating threads are clean and free of debris before assembly. Do not substitute Grade 5 or Grade 2 nuts on Grade 8 cap screws in structural applications without engineering approval.
