Value Collection 39074 Hex Head Cap Screw 3/8-16 X 8 in Grade 8

Product Description

The VALUE COLLECTION 39074 is a partially threaded hex head cap screw sized 3/8-16 x 8 inches, manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 is a high-strength fastener classification rated for demanding structural and mechanical applications where superior tensile and proof load values are required. The zinc yellow dichromate coating provides corrosion resistance suitable for general industrial environments. This screw conforms to ASME B18.2.1 dimensional standards, making it a direct fit for applications where specification compliance is required. Tradespeople, millwrights, maintenance technicians, and equipment assemblers work with this fastener type across a broad range of mechanical assemblies.

This hex head cap screw is suited for use in heavy equipment assembly, structural steel connections, machinery mounting, and industrial maintenance applications. The partially threaded shank is appropriate where a smooth bearing surface under the head is needed to prevent thread engagement through the full grip length. The UNC thread form is the standard coarse-thread series, compatible with standard UNC nuts, tapped holes, and threaded inserts commonly found in North American mechanical systems. Package quantity is 10 units per order.

Key Features

• Grade 8 steel construction for high tensile strength in demanding mechanical applications
• Zinc yellow dichromate finish provides corrosion protection in general industrial environments
• Partially threaded shank allows proper clamping without thread contact through the full grip
• 3/8-16 UNC thread form compatible with standard coarse-thread hardware
• Conforms to ASME B18.2.1 dimensional standards
• Sold in packs of 10 with a minimum order quantity of 1

Compatibility

Designed for use in standard 3/8-16 UNC tapped holes, hex nuts, and threaded inserts conforming to ASME B18.2.1 specifications. Suitable for structural, mechanical, and industrial assembly applications requiring Grade 8 fastener strength.

Installation Notes

Installation should be performed by a qualified technician or mechanic familiar with fastener torque requirements for Grade 8 hardware. Always de-energize and isolate the assembly before working on fastened joints in powered equipment. Use the appropriate hex drive tool or socket to avoid rounding the head. Do not substitute a lower-grade fastener in any joint specified for Grade 8.
