Value Collection D39062 Hex Head Cap Screw 3/8-16 X 3 in

Product Description

The VALUE COLLECTION D39062 is a 3/8-16 hex head cap screw measuring 3 inches under the head, manufactured from Grade 8 steel with a zinc yellow dichromate finish. Partially threaded and dimensioned to ASME B18.2.1 standards, this fastener is suited for high-strength bolted assemblies where tensile load and corrosion resistance are both critical. The Grade 8 rating indicates a minimum tensile strength well above that of common Grade 5 fasteners, making it appropriate for structural, mechanical, and equipment-mounting applications. The zinc yellow dichromate finish provides a base level of corrosion resistance and is visually identifiable by its distinctive gold-yellow tone. Installed by millwrights, maintenance technicians, and general contractors.

This screw is used across a wide range of industrial, commercial, and mechanical applications requiring a high-strength unified coarse thread (UNC) fastener in the 3/8-16 size. Typical installations include machinery frames, bracket assemblies, equipment bases, and structural connections where a partially threaded grip zone is needed to clamp material cleanly without thread engagement through the full joint. The 3-inch length accommodates moderate to thick material stacks. Sold individually with a minimum order quantity of 10 pieces.

Key Features

• Grade 8 steel construction for high tensile and shear strength in demanding assemblies
• Zinc yellow dichromate finish provides corrosion resistance and visual grade identification
• Partially threaded shank creates a smooth grip zone for accurate clamping
• UNC 3/8-16 thread form for broad compatibility with standard nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standards for consistent head geometry and thread runout
• 3-inch length under head suits moderate material stack depths

Compatibility

Designed for use with standard 3/8-16 UNC nuts, washers, and tapped holes conforming to ASME and ANSI inch-series fastener standards. Suitable for any application specifying a Grade 8 hex cap screw in 3/8-16 x 3-inch partially threaded configuration.

Installation Notes

Installation is performed by qualified maintenance technicians, millwrights, or mechanical contractors using a standard hex wrench or socket set. Always confirm hole clearance and thread engagement depth before torquing. Refer to published Grade 8 torque specification tables for the 3/8-16 thread size and the specific joint material. Do not mix Grade 8 fasteners with lower-grade nuts, as the nut may strip before the fastener reaches its rated clamp load.
