Tri-Groove-Drive Tamper-Resistant Nuts

Tri-groove-drive nuts are narrower than sloped and drilled-spanner-drive nuts to fit in tight spaces. Install with a tri-groove socket and either a socket driver or an open-end wrench (all sold separately). Use them to reduce the risk of unwanted removal for objects in public spaces such as signs, lighting fixtures, and displays.

Zinc—Zinc nuts are lightweight and corrosion resistant in wet environments.

Zinc-Plated Steel—Zinc-plated steel nuts are coated to protect the steel from corrosion in wet environments.

316 Stainless Steel—316 stainless steel nuts won’t corrode from water, chemicals, or salt spray.
