Value Collection MP39364 Hex Cap Screw 3/8-24 X 3-1/2 in Grade 8

Product Description

The Value Collection MP39364 is a partially threaded hex head cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. Built to Grade 8 steel, it delivers a tensile strength suitable for demanding load-bearing joints where lesser grades would fail. The 3/8-24 UNF thread pitch provides fine-thread engagement for applications requiring precise clamping force or resistance to vibration loosening. A zinc yellow dichromate finish provides corrosion resistance and identifies the Grade 8 rating at a glance. Manufactured to ASME B18.2.1 standards, the fastener ensures dimensional consistency across production runs. Package quantity is 10 pieces per order.

This cap screw is suited for use in heavy machinery, automotive assemblies, hydraulic component mounting, and general industrial fabrication where high-tensile fasteners are specified. The 3/8-24 fine thread is common in precision mechanical joints and is frequently called out in OEM service documentation for equipment requiring vibration-resistant fastening. The partially threaded shank provides a bearing surface in clearance-hole applications, making it appropriate for through-bolt and clamped-joint configurations. Installation is performed by machinists, millwrights, mechanics, and maintenance technicians across manufacturing and field service environments.

Compatibility

Designed as a standard ASME B18.2.1 inch-series hex head cap screw compatible with any 3/8-24 UNF tapped hole or clearance-hole assembly specifying a Grade 8 fastener.

Installation Notes

Installation should be performed by qualified mechanics or technicians familiar with fastener torque specifications for Grade 8 hardware. Always verify hole thread class and surface condition before installation. Apply thread lubricant or thread-locking compound as specified by the equipment OEM. Use a calibrated torque wrench to achieve the required clamp load without exceeding the fastener proof load.
