Value Collection D39362 Hex Head Cap Screw 3/8-24 X 3 in Grade 8

Product Description

The VALUE COLLECTION D39362 is a Grade 8 steel hex head cap screw sized 3/8-24 x 3 inches, finished in zinc yellow dichromate for corrosion resistance. It is partially threaded and conforms to ASME B18.2.1 dimensional standards. The 3/8-24 thread designation indicates a Unified National Fine (UNF) thread form, which provides greater tensile strength and resistance to loosening under vibration compared to coarse-thread fasteners. Grade 8 construction means this screw is suited for high-load, high-stress fastening applications. Licensed tradespeople and maintenance professionals working in mechanical, structural, or industrial assembly commonly specify this fastener.

This cap screw is appropriate for demanding fastening applications in industrial machinery, automotive assemblies, and heavy mechanical equipment where high shear and tensile loads are present. The fine UNF thread pattern makes it well suited for use in tapped holes in harder materials or in applications requiring precise torque control and secure clamping force. The partial thread configuration allows for a smooth shank section to bear shear loads along the joint interface.

Key Features

• Grade 8 steel construction for high tensile and proof load capacity
• 3/8-24 UNF thread for fine-pitch engagement and vibration resistance
• 3-inch length under head for extended grip range
• Partially threaded shank to handle shear loads at the joint
• Zinc yellow dichromate finish provides corrosion protection
• Meets ASME B18.2.1 dimensional standards

Compatibility

Designed as an OEM-style replacement or standard-stock hex head cap screw for applications requiring a 3/8-24 UNF, Grade 8, partially threaded fastener conforming to ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with fastener torque specifications for Grade 8 hardware. De-energize and lock out any equipment before servicing fastened assemblies. Use a properly sized hex socket or wrench to avoid rounding the hex head. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.
