Holo-krome 07026 Socket Jam Screw 7/8-14 Unf Alloy Steel

Product Description

The HOLO-KROME 07026 is a socket jam screw designed for applications requiring a low-profile threaded fastener that locks against another nut or component to prevent loosening. This screw features a 7/8-14 UNF thread - a fine-pitch unified national fine thread - and an overall length of 7/16 inches, making it compact and suited for tight assemblies. Drive is via a 1/2-inch hex key (Allen wrench). Constructed from alloy steel with an uncoated finish, it delivers solid mechanical strength for general industrial and mechanical fastening tasks. Installation is performed by maintenance technicians and mechanical assemblers working on threaded assemblies where jam-nut style locking is required.

The HOLO-KROME 07026 is used in mechanical assemblies where a standard full-height nut cannot be accommodated or where a secondary locking fastener is needed to secure a primary nut or threaded component. The fine 7/8-14 UNF thread pitch allows precise torque control and tight seating. Typical applications include machine tool assemblies, industrial equipment, and mechanical linkages that demand reliable thread engagement in confined spaces. This screw is sold in multiples of 5 as a minimum order quantity.

Key Features

• 7/8-14 UNF fine-pitch thread for precise engagement and controlled fastening
• 7/16-inch overall length provides a low-profile jam-nut style profile
• 1/2-inch hex key drive for installation with a standard Allen wrench
• Alloy steel construction for reliable mechanical strength
• Uncoated finish - suitable for applications where additional coating is not required

Compatibility

Designed as an OEM-style replacement or service fastener for mechanical assemblies using 7/8-14 UNF threaded interfaces requiring a socket jam screw.

Installation Notes

Installation is performed by qualified mechanical technicians or assemblers using a 1/2-inch hex key. Ensure the mating threaded bore is clean and free of debris before installation. De-energize and lock out any equipment before servicing fasteners in live machinery. Do not exceed the torque capacity appropriate for the alloy steel material grade and thread size as specified by the governing assembly documentation.
