4 Lugnuts Acorn Bulge 7/16

The Gorilla 4 Lugnuts Acorn Bulge 7/16 (SKU GOR91177HTB) is a premium set of four replacement lug nuts engineered for reliable wheel attachment and secure fastening across a wide range of vehicles. These right-hand thread acorn bulge lug nuts feature a 7/16-20 thread pitch and 13/16-inch hex head, delivering the precision fitment and holding power required for both daily driving and demanding off-road recovery operations.

Each lug nut is manufactured from heat-treated steel with a durable chrome finish that resists corrosion and maintains appearance through extended exposure to road salt, moisture, and environmental contaminants. The 60-degree seating angle and closed-end design ensure consistent clamping force distribution across the wheel mounting surface, while the acorn bulge profile provides additional strength at the critical load-bearing junction. Heat treatment enhances tensile strength and resistance to vibration loosening—a key consideration for vehicles experiencing high torque cycles or sustained vibration during highway or trail operation.

This four-piece set addresses the complete wheel assembly on single-wheel vehicles or serves as a replacement set for vehicles requiring lug nut maintenance. Users in automotive service, fleet management, off-road recovery, and vehicle restoration rely on Gorilla lug nuts for their proven durability and compatibility with standard wheel mounting systems. The chrome finish and closed-end construction make these lug nuts suitable for both functional duty and appearance-conscious applications where wheel presentation matters.

Gorilla has established itself in the fastening market as a manufacturer prioritizing consistent quality and corrosion resistance. The 7/16-20 thread specification is standard across most light-duty and medium-duty truck and SUV applications, making these lug nuts a versatile replacement option for common vehicles. The set weighs 0.52 lbs and measures 2.5 x 1.1 x 4.1 inches, enabling straightforward storage and transport in any vehicle toolkit or service facility.
