Lug Nut and Lock System 1/2in Acorn Bulge Chrome

The GORILLA Lug Nut and Lock System 1/2in Acorn Bulge Chrome (Part #91783) is a complete wheel security solution designed to prevent theft and unauthorized wheel removal on vehicles and trailers. This kit combines 16 chrome-plated steel lug nuts with 4 matching security locks, providing comprehensive protection for a full set of wheels while maintaining a cohesive, professional appearance under the vehicle.

The 1/2-20 right-hand thread specification ensures universal compatibility with standard metric and domestic wheel installations across most vehicles. The acorn bulge design offers both aesthetic refinement and functional durability, with the chrome finish resisting corrosion and maintaining appearance through exposure to road salt, moisture, and harsh weather conditions. The combination of 16 standard lug nuts with 4 security locks means each wheel receives one locking nut while maintaining consistent torque distribution across all fastening points—a critical consideration for balanced wheel assembly and safe operation at highway speeds.

This system suits fleet operators, long-haul trucking operations, construction and utility vehicle owners, and anyone protecting high-value wheels from opportunistic theft in unattended situations. The stainless steel construction and chrome plating extend service life in demanding environments. Security-minded vehicle owners value the deterrent effect of keyed lug nuts on standard commercial and aftermarket wheel sets, making this kit essential for heavy equipment, trailers, and vehicles parked in public or semi-secured locations.

GORILLA has built its reputation in the automotive fastener space by prioritizing corrosion resistance and theft-prevention engineering. This lug nut and lock system represents the brand's commitment to protective hardware that performs reliably across seasons and climates while remaining straightforward to install with standard wheel removal tools.
