Value Collection MP39356 Hex Cap Screw 3/8-24 X 1-1/2 in Grade 8

Product Description

The VALUE COLLECTION MP39356 is a 3/8-24 UNF hex head cap screw manufactured from Grade 8 steel with a zinc yellow dichromate finish. It measures 1-1/2 inches under the head and is partially threaded, conforming to ASME B18.2.1 dimensional standards. Grade 8 steel provides high tensile strength suitable for demanding mechanical and structural fastening applications. The zinc yellow dichromate coating offers corrosion resistance and is visually identifiable by its gold-yellow appearance. This fastener is sold in a package quantity of 25 pieces and is installed by mechanics, millwrights, machinists, and maintenance technicians across industrial and commercial settings.

This screw is suited for high-strength bolted assemblies where a fine-thread UNF fastener is required. The 3/8-24 thread pitch provides finer thread engagement compared to UNC, making it a common choice in applications requiring greater tension load capacity or use in thinner-walled tapped holes. Typical installations include equipment frames, machinery brackets, and structural joints in automotive, HVAC equipment, and general industrial assemblies. The partial threading allows for a smooth shank section, which is preferred in applications where shear loads or precise hole alignment are a factor.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 3/8-24 UNF fine thread for greater clamping force and vibration resistance
• Zinc yellow dichromate finish provides corrosion resistance and easy visual identification
• Partially threaded shank for shear load applications and precise alignment
• Conforms to ASME B18.2.1 dimensional standards
• Sold in a package of 25 pieces

Compatibility

Designed as a standard ASME B18.2.1 hex head cap screw suitable for use in any application requiring a 3/8-24 UNF Grade 8 partially threaded fastener with a 1-1/2 inch length under head.

Installation Notes

Install using the appropriate hex wrench or socket drive sized for a 3/8-inch hex head cap screw. De-energize and lock out any equipment before performing fastener installation or removal on live machinery, following applicable OSHA lockout/tagout procedures. Torque to the value specified by the equipment manufacturer or applicable engineering standard for Grade 8 fasteners of this diameter and thread pitch. Do not substitute a lower-grade fastener in applications specifying Grade 8.
