Value Collection 451026BR Hex Cap Screw 1-1/8-12x10 Grade 8

Product Description

The VALUE COLLECTION 451026BR is a heavy-duty hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at 1-1/8-12 UNF thread with a 10-inch length under head, this partially threaded fastener is manufactured from Grade 8 steel with a bright, uncoated finish. Grade 8 is a high-strength classification suited for demanding bolted joints where tensile and proof load requirements exceed what lower-grade hardware can handle. The screw conforms to ASME B18.2.1 dimensional standards, ensuring consistent head geometry and thread form across applications. It weighs 3.13 pounds and is sold individually.

This cap screw is appropriate for heavy equipment assembly, structural steel connections, agricultural machinery, and industrial fabrication where high-torque, high-load fastening is required. The 1-1/8-12 UNF thread form provides finer thread pitch relative to UNC of the same diameter, offering improved thread engagement strength and better resistance to loosening under vibration. The partial threading leaves a smooth shank section under the head, which is standard for long fasteners at this diameter and length.

Key Features

• Grade 8 steel construction for high tensile and proof load capacity
• 1-1/8-12 UNF thread form with 10-inch length under head
• Partially threaded shank per standard long-fastener geometry
• Bright, uncoated finish — compatible with applications where coating is specified separately or not required
• Conforms to ASME B18.2.1 dimensional standards
• 1-11/16 inch hex key size for proper wrench engagement

Compatibility

Designed as a standard ASME B18.2.1 hex head cap screw suitable for any application calling for a 1-1/8-12 UNF Grade 8 partially threaded fastener of 10-inch length under head.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or structural assembly personnel using a 1-11/16 inch hex wrench or appropriate socket. Apply torque values per the applicable engineering specification or fastener torque chart for Grade 8 hardware at this diameter. Verify mating thread condition and ensure threads are clean and free of debris before installation. Use appropriate thread lubricant or anti-seize only when specified by the joint design, as lubrication affects torque-tension relationships.
