Open End Lug Nuts

Open End Lug Nuts

Open end lug nuts are bored straight through, so the stud can extend past the nut, needed for long studs, stud conversions and some ATV and trailer setups. Stocked in 10x1.25, 12x1.25, 12x1.5, 12x1.75, 14x1.5, 14x2, 16x1.5, 3/8", 1/2", 7/16", 9/16".

Find your thread size: 12x1.5, 12x1.25, 12x1.75, 14x1.5, 14x2, 7/16", 1/2" and 9/16".

When open end is the right call

Choose open end when your studs are longer than a closed cap allows, common after extended-stud installs or on adapters. Available in bulge acorn styles, standard and short lengths, open end throughout.

Common questions

Open end or closed end, does it matter for strength? No difference in clamping strength at proper torque. The choice is about stud length and appearance.

Do open end nuts rust on the exposed stud? The exposed tip can surface-rust in snow-belt states; it is cosmetic and cleans up with a wire brush at rotation. Keep lubricants and anti-seize off wheel stud threads, since torque specs assume clean, dry threads.

Are these right for wheel adapters? Often yes: adapter studs sometimes sit long, and open end nuts accommodate them. Check your adapter's stud length against the nut's bore depth.

See the torque reference chart for tightening specs and the fitment guide to confirm your thread size.
