Value Collection BH031F175N Hex Head Cap Screw 5/16-24

Product Description

The VALUE COLLECTION BH031F175N is a Grade 8 steel hex head cap screw with a 5/16-24 UNF thread and a 1-3/4 inch length under head. It carries a zinc-plated finish for corrosion resistance and meets ASTM A354 BD and MIL-HDBK-57 standards. This fastener is used in high-strength bolting applications where fine-thread engagement and superior tensile strength are required. It is installed by HVAC technicians, plumbers, electricians, pipefitters, and general tradespeople working on equipment assemblies, brackets, flanges, and structural connections in commercial and industrial settings.

This cap screw is suited for applications requiring fine-thread, high-strength fastening in steel assemblies. Its Grade 8 rating makes it appropriate for load-bearing connections in mechanical equipment, control panels, unit supports, and similar trade installations. The zinc plating provides a base level of protection in mildly corrosive environments, making it a practical choice for interior mechanical rooms and equipment enclosures.

Key Features

• Grade 8 steel construction provides high tensile and proof-load strength
• 5/16-24 UNF fine-thread pattern for precise torque control and reduced loosening under vibration
• Zinc-plated finish for corrosion resistance in standard indoor service environments
• Meets ASTM A354 BD and MIL-HDBK-57 standards for material and dimensional consistency
• 1-3/4 inch length under head accommodates medium-depth fastening applications

Compatibility

Designed as a standard UNF hex head cap screw for use in any application requiring a 5/16-24 threaded fastener with Grade 8 strength and zinc-plated finish.

Installation Notes

Install using a standard hex wrench or socket set sized for a 5/16-24 fastener. Always power down or de-energize equipment before working on assemblies that require fastener removal or replacement. Use a calibrated torque wrench to meet equipment manufacturer or applicable code torque requirements. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.
