Value Collection 99186 Hex Head Cap Screw 3/4-10 X 7 in Grade 8

Product Description

The VALUE COLLECTION 99186 is a Grade 8 steel hex head cap screw in a 3/4-10 UNC thread size with a 7-inch length under head. Partially threaded along its shank, this fastener is built to handle high-strength bolting applications where clamp load and shear resistance are critical. Grade 8 designation indicates a medium carbon alloy steel heat-treated to meet elevated tensile and proof load requirements. The uncoated finish leaves the bare steel surface exposed, making it suitable for use where a specific coating will be applied in the field or where coating is not required by the assembly spec. Manufactured to ASME B18.2.1 and SAE J429 standards.

This cap screw is used in heavy-duty mechanical assemblies, structural connections, and industrial equipment where Grade 8 strength is specified. Typical installations include agricultural equipment, construction machinery, heavy fabrications, and structural steel applications. The 3/4-10 UNC thread pitch is one of the most common coarse-thread sizes in industrial and OEM assembly, and the 7-inch body length accommodates thicker material stacks that shorter fasteners cannot span. Sold in a package quantity of 10.

Key Features

• Grade 8 steel construction meets high tensile and proof load requirements per SAE J429
• Partially threaded shank provides a bearing surface and resists lateral shear in the grip area
• 3/4-10 UNC coarse thread for broad tool and nut compatibility
• 7-inch length under head accommodates thick material stacks and long-grip assemblies
• Uncoated finish suitable for field coating or bare-steel applications
• Conforms to ASME B18.2.1 and SAE J429 dimensional and mechanical standards

Compatibility

Designed for use in any application specifying a 3/4-10 UNC Grade 8 hex head cap screw with a 7-inch length under head per ASME B18.2.1 and SAE J429.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or mechanical assemblers using standard 1-1/8-inch hex tooling for 3/4-inch fasteners. Always use a hardened flat washer and a Grade 8 compatible nut to maintain the rated clamp load. Torque to the assembly specification provided by the equipment manufacturer or structural engineer of record — do not estimate torque without a reference value. Inspect threads for contamination or damage before installation; do not install fasteners with rolled or cross-threaded starts.
