Value Collection 440482BR Hex Cap Screw 5/8-11 X 1 in Grade L9

Product Description

The VALUE COLLECTION 440482BR is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. Manufactured from Grade L9 alloy steel, this fastener delivers superior tensile strength compared to standard Grade 5 or Grade 8 fasteners, making it well-suited for demanding bolted joints. The 5/8-11 UNC thread form pairs with a 1-inch length under head, and the zinc yellow dichromate finish provides a corrosion-resistant barrier while serving as a visual indicator of its high-strength classification. Licensed mechanics, millwrights, and maintenance technicians are the primary installers of this fastener type.

This cap screw is used in heavy-duty machinery, agricultural equipment, off-highway vehicles, and structural connections where high clamp load and fatigue resistance are required. The fully threaded shank allows engagement along the entire grip length, making it particularly effective in short-bolt applications where maximum thread engagement is needed. The 5/8-11 UNC thread standard is widely used across American industrial equipment, and the 15/16-inch hex drive size is compatible with standard socket and wrench sets. Sold individually with a minimum order quantity of 10 pieces.

Compatibility

Designed as a high-strength replacement or service fastener for applications requiring a 5/8-11 UNC fully threaded hex head cap screw in Grade L9 alloy steel.

Installation Notes

Installation should be performed by a qualified mechanic or millwright following applicable torque specifications for Grade L9 fasteners as defined by the equipment manufacturer or relevant ASME or SAE standards. Always inspect mating threads for damage before installation and use a calibrated torque wrench to achieve proper clamp load. Do not substitute a lower-grade fastener in a Grade L9-specified joint, as doing so can result in joint failure. Minimum order quantity of 10 must be observed when ordering this SKU.
