Holo Krome Nut

Holo Krome nuts are precision socket-drive jam nuts, also called Allen nuts or socket set screw nuts. They are made for low-profile fastening and for locking threaded components in place. The internal hex socket lets you tighten the nut with a standard hex key (Allen wrench). This works well where a conventional external hex nut is hard to reach with a wrench.

Key Features:

• Internal hex socket drive for tightening with a hex key
• Low-profile jam nut design for tight spaces and a clean, flush appearance
• Useful for locking adjustments, set screws and threaded studs
• Made by Holo-Krome, a recognized name in socket-head fasteners
• Suited to machinery, tooling, automotive, powersports and general industrial use

Holo Krome nuts give you a secure, repeatable fastening solution where a low profile and hex-key access matter. Use the options on this page to choose the thread and style you need.
