Value Collection 39244 Hex Head Cap Screw 1-1/4-7 X 5 in Grade 8

Product Description

The VALUE COLLECTION 39244 is a Grade 8 steel hex head cap screw with a 1-1/4-7 UNC thread and a 5-inch length under head. It features a zinc yellow dichromate finish that provides corrosion resistance in demanding service environments. The fastener is partially threaded and manufactured to ASME B18.2.1 standards, making it suitable for structural and mechanical assemblies where high tensile strength and dimensional consistency are required. Installation is driven with a 1-7/8-inch hex key or matching socket. This screw is used by millwrights, maintenance technicians, and mechanical contractors working on heavy equipment, machinery frames, and structural connections.

This cap screw is well-suited for high-load bolted joint applications in industrial, commercial, and heavy-equipment settings. The partial threading allows the unthreaded shank to bear shear loads, which is common in machinery mounts, flanged connections, and structural steel assemblies. Sold in a package quantity of two per order.

Key Features

• Grade 8 steel construction for high tensile and proof load requirements
• Zinc yellow dichromate finish for corrosion protection
• Partially threaded shank supports shear load applications
• 1-1/4-7 UNC thread form per standard coarse-thread series
• Manufactured to ASME B18.2.1 dimensional standards
• Driven with a 1-7/8-inch hex key or socket

Compatibility

Designed as a standard-dimension Grade 8 hex head cap screw for use in any bolted assembly requiring a 1-1/4-7 UNC thread and 5-inch grip length where ASME B18.2.1 compliance is specified.

Installation Notes

Installation should be performed by a qualified millwright, mechanical technician, or contractor familiar with high-strength fastener procedures. Verify mating thread condition and hole alignment before assembly. Apply appropriate thread lubricant or fastener compound per your project specification before torquing. Always follow applicable industry standards and engineering specifications for torque values on Grade 8 fasteners in structural applications.
