Value Collection BH038C150N Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION BH038C150N is a 3/8-16 x 1-1/2 inch hex head cap screw manufactured from Grade 8 steel with a zinc-plated finish. Grade 8 fasteners carry a higher proof load and tensile strength than Grades 2 or 5, making them appropriate for high-stress mechanical and structural assemblies. The zinc coating provides a baseline level of corrosion resistance in general-purpose indoor and sheltered outdoor environments. This screw follows UNC (Unified National Coarse) thread standards and meets ASTM A354 BD and MIL-HDBK-57 specifications. It is driven with a 9/16-inch hex wrench or socket and is measured under the head. Maintenance technicians, millwrights, and general tradespeople commonly use this fastener in equipment assembly and repair work.

This fastener is suited for mechanical assemblies, equipment mounting, structural brackets, and machinery repair across commercial and industrial settings. The 3/8-16 UNC thread is one of the most common coarse-thread sizes found in North American equipment, making this screw a practical stock item for maintenance shops, service vehicles, and job-site supply. Applications span HVAC equipment mounting, electrical enclosure assembly, and general fabrication where a high-strength, zinc-protected hex fastener is called for.

Key Features

• Grade 8 steel construction meets elevated tensile and proof load requirements for demanding mechanical assemblies
• Zinc-plated finish provides corrosion resistance for general-purpose use
• 3/8-16 UNC thread — a widely standardized coarse-thread size compatible with common tapped holes and nuts
• 1-1/2 inch length measured under the head for consistent stack-up calculations
• Meets ASTM A354 BD and MIL-HDBK-57 standards
• Driven with a 9/16-inch hex socket or wrench — no specialty tooling required

Compatibility

Designed for use in any application requiring a 3/8-16 UNC coarse-thread hex head cap screw with Grade 8 strength and zinc finish, including equipment mounting, structural connections, and general mechanical assembly where ASTM A354 BD compliance is specified.

Installation Notes

Installation requires a 9/16-inch socket, box-end wrench, or torque wrench. Always verify that the mating tapped hole or nut matches the 3/8-16 UNC thread specification before installation. Do not mix Grade 8 fasteners with lower-grade nuts or hardware in high-load joints. Follow the applicable equipment manufacturer torque specifications and any relevant codes for the assembly type; do not substitute assumed torque values.
