Value Collection 39386 Hex Cap Screw 7/16-20 X 2-3/4 in Grade 8

Product Description

The VALUE COLLECTION 39386 is a partially threaded hex head cap screw engineered for high-strength bolted assemblies in industrial, mechanical, and structural applications. Manufactured from Grade 8 steel and finished with a zinc yellow dichromate coating, this fastener delivers strong corrosion resistance alongside the elevated tensile and proof-load requirements of Grade 8 hardware. The 7/16-20 thread designation indicates a fine-thread UNF profile at 7/16 inch nominal diameter, with a 2-3/4 inch length under head. Partial threading leaves a smooth shank section near the head, making it well-suited for applications requiring precise shear load transfer or controlled clamp zones. This screw is sold in a 25-piece package.

This fastener is used across a wide range of trade and industrial settings, including equipment assembly, machinery mounting, structural brackets, and heavy-duty mechanical connections. Fine-thread UNF fasteners are commonly specified where vibration resistance and precise torque control are priorities. Grade 8 hardware is a standard choice for OEM equipment, agricultural machinery, and heavy transportation applications. This item conforms to ASME B18.2.1 and SAE J429 standards, making it appropriate for applications with documented specification requirements.

Key Features

• Grade 8 steel construction meets SAE J429 proof load and tensile strength requirements
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• 7/16-20 UNF fine thread profile for improved vibration resistance and torque control
• Partially threaded shank supports shear load transfer in close-tolerance holes
• Conforms to ASME B18.2.1 dimensional standards
• Sold in a 25-piece package with a minimum order quantity of 1

Compatibility

Designed as a standard Grade 8 UNF hex head cap screw suitable for use in any application calling for a 7/16-20 partially threaded fastener conforming to ASME B18.2.1 and SAE J429 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with torque specifications for Grade 8 fasteners. Always verify that mating threads are clean, undamaged, and of compatible thread class before assembly. Use a calibrated torque wrench and follow the torque values specified by the equipment manufacturer or applicable engineering standards. Partial-thread screws should be seated so the smooth shank spans the joint interface where shear load transfer is intended.
