Value Collection C703325 Hex Head Cap Screw 9/16-18 X 4 in

Product Description

The VALUE COLLECTION C703325 is a Grade 8 steel hex head cap screw with a 9/16-18 UNF thread and a 4-inch length under head. This is a partially threaded fastener, meaning a portion of the shank remains unthreaded to provide bearing strength and shear resistance in bolted joints. The bright uncoated finish meets ASME B18.2.1 dimensional standards. It is used in high-strength mechanical assemblies across industrial, HVAC structural, and trade construction applications where Grade 8 tensile performance is required.

This cap screw is suited for heavy-duty bolted connections in mechanical and structural assemblies. Typical applications include equipment mounting, bracket fastening, and frame connections where a high-strength inch-series UNF fastener is specified. The partial thread design is common in through-bolt applications where the unthreaded shank spans a joint interface. Sold in packages of 25, this screw is appropriate for shop stock, service vans, and job-site use by HVAC technicians, millwrights, plumbers, and general mechanical contractors.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 9/16-18 UNF thread provides fine-thread engagement for vibration-prone assemblies
• Partially threaded shank allows full bearing load across joint interfaces
• Bright uncoated finish meets ASME B18.2.1 dimensional standards
• Inch measurement system compatible with standard SAE tooling
• Package quantity of 25 supports stocking and multi-fastener jobs

Compatibility

Designed for use in any application requiring a 9/16-18 UNF Grade 8 hex head cap screw conforming to ASME B18.2.1. Compatible with standard hex nuts, flange nuts, and threaded components using 9/16-18 UNF inch-series thread forms.

Installation Notes

Installation is performed with a standard 7/8-inch hex wrench or socket driver. Verify that mating threaded components are also rated for Grade 8 load requirements before assembly. Ensure joint surfaces are clean and free of debris before seating. Do not mix metric and inch-series fasteners in the same joint assembly.
