Value Collection MP39357 Hex Cap Screw 3/8-24 Grade 8 25-pack

Product Description

The VALUE COLLECTION MP39357 is a 3/8-24 UNF partially threaded hex head cap screw manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 steel delivers high tensile strength suitable for demanding fastening applications where standard hardware-grade fasteners would fail. The zinc yellow dichromate coating provides corrosion resistance and is visually identifiable by its gold-yellow appearance. At 1-3/4 inches in length under head, this screw meets ASME B18.2.1 dimensional standards. It is sold in packages of 25 and is used by mechanical contractors, industrial maintenance technicians, and trade professionals requiring a reliable, specification-grade fastener.

This hex head cap screw is appropriate for use in mechanical assemblies, structural joints, and equipment mounting applications where Grade 8 tensile strength is specified. The 3/8-24 UNF thread form is a fine-pitch designation, making it well suited for applications requiring precise clamping force and resistance to vibration loosening. Common install scenarios include machinery frames, brackets, and components subject to dynamic loading. Partial threading allows the unthreaded shank to bear shear loads while the threaded portion provides clamping.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 3/8-24 UNF fine-pitch thread for vibration-resistant clamping
• Partially threaded shank to carry shear loads at the joint
• Zinc yellow dichromate finish for corrosion resistance and coating identification
• Meets ASME B18.2.1 dimensional standards
• Packaged in quantities of 25 for shop stock or jobsite use

Compatibility

Designed for use in standard 3/8-24 UNF tapped holes and with matching 3/8-24 hex nuts and washers per ASME B18.2.1 specifications. Suitable for any application specifying a Grade 8 partially threaded hex cap screw in inch measurement.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with fastener torque requirements for Grade 8 hardware. Always de-energize, depressurize, or otherwise render safe any equipment before disassembling fastened joints. Use a calibrated torque wrench and apply torque values specified by the equipment manufacturer or applicable engineering standards. Do not substitute Grade 8 fasteners with lower-grade hardware in joints where Grade 8 is specified.
