Value Collection 451193BR Hex Head Cap Screw 1-14 Grade 8

Product Description

The VALUE COLLECTION 451193BR is a Grade 8 steel hex head cap screw sized at 1-14 UNF with a 7.5-inch length under head. It is partially threaded and left uncoated (bright finish), conforming to ASME B18.2.1 dimensional standards. This fastener is suited for high-strength bolted connections in heavy equipment, structural assemblies, and industrial machinery. The Grade 8 designation indicates a high-tensile carbon steel construction capable of handling demanding clamp loads. Installation requires a 1.5-inch hex key or wrench. Licensed trades and maintenance professionals working in mechanical, industrial, or construction environments are the primary installers.

This cap screw is used in applications requiring a high-strength inch-series UNF fastener. The 1-14 thread designation is a unified fine thread, offering finer pitch and higher resistance to loosening under vibration compared to coarse-thread equivalents. The 7.5-inch length under head accommodates thicker material stackups or deep through-bolt applications. It is appropriate for use in industrial equipment assembly, heavy-duty machinery maintenance, and structural bolted connections where Grade 8 tensile ratings are specified by engineers or original equipment manufacturers.

Key Features

• Grade 8 steel construction for high-tensile strength bolted connections
• 1-14 UNF thread for fine-pitch engagement and vibration resistance
• 7.5-inch length under head suits deep or thick material applications
• Partially threaded shank provides a bearing surface for shear-load applications
• Bright uncoated finish — no plating that could affect dimensional tolerances
• Conforms to ASME B18.2.1 for dimensional consistency

Compatibility

Designed as a standard inch-series hex head cap screw per ASME B18.2.1, suitable for use in any application specifying a 1-14 UNF Grade 8 fastener with a 7.5-inch length under head.

Installation Notes

Installation requires a 1.5-inch open-end, box-end, or socket wrench. Always verify the mating thread is clean and undamaged before installation. Torque to the value specified by the equipment manufacturer or engineering drawing for Grade 8 fasteners of this diameter — do not use generic torque values without confirming the joint design. De-energize, depressurize, or otherwise make safe any assembly before removing or replacing structural fasteners.
