Value Collection D39087 Hex Head Cap Screw 7/16-14 X 3 in

Product Description

The VALUE COLLECTION D39087 is a partially threaded hex head cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers superior tensile strength and corrosion resistance compared to lower-grade alternatives. The 7/16-14 UNC thread pattern and 3-inch length under head make it well-suited for bolted connections requiring a secure, torque-resistant grip. Licensed mechanics, millwrights, pipefitters, and maintenance technicians rely on Grade 8 hardware when joint integrity under load is non-negotiable. Meets ASME B18.2.1 dimensional standards.

This cap screw fits a wide range of heavy-duty bolted joint applications where a standard UNC inch-series fastener is specified. Partial threading allows the unthreaded shank to bear shear loads, making it appropriate for close-tolerance through-bolt applications in machinery, equipment frames, structural brackets, and general fabrication. It is sold individually with a minimum order quantity of 10 pieces, making it practical for both repair stock and production assembly use.

Key Features

• Grade 8 steel construction provides high tensile and proof load strength for demanding bolted joints
• Zinc yellow dichromate finish offers corrosion resistance and visual identification as a high-strength fastener
• Partially threaded shank supports shear load transfer in through-bolt applications
• 7/16-14 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• Meets ASME B18.2.1 dimensional and tolerance standards
• 3-inch length under head accommodates moderate-depth clamping stacks

Compatibility

Designed as a standard inch-series hex head cap screw for use with any 7/16-14 UNC tapped hole, nut, or threaded insert in structural, mechanical, or equipment assembly applications.

Installation Notes

Installation is typically performed by mechanics, millwrights, or maintenance technicians using a standard hex wrench or impact driver with the appropriate socket. Always consult applicable torque specifications from the joint design or equipment manufacturer before final tightening — do not estimate torque for Grade 8 fasteners in critical applications. Ensure mating threads are clean and free of debris before assembly. Where applicable, follow relevant ASME or OEM fastener installation guidelines.
