Open Nut, 60° Taper, 19 Hex, 17 Height

This is an open-ended wheel nut designed with a 60° conical (tapered) seat and a 19mm hex, in a compact 17mm overall height. The open-end format leaves the stud tip exposed, which can be useful where stud length varies or where closed nuts may bottom out.

Open conical nuts are widely sold for conical-seat wheels and are often used where the stud length is unknown/variable, but this is a general industry use-case context only.

60° Conical Seat Type

A 60° conical seat uses a matching tapered surface in the wheel’s bolt hole to centre and clamp the wheel. This seat type must match the wheel; conical nuts should only be used with wheels that specify a conical seat. 

Common Applications

• Aftermarket and OEM wheels that specify a 60° taper seat (fitment varies by vehicle and wheel)
• Vehicles using any of the listed thread variants (select the correct variant for your hub/studs)
• Commonly seen across mixed fitments, including European and Japanese applications, depending on thread pitch (confirm before ordering)

Open nuts are commonly chosen for wheels with a conical seating face, including many aftermarket alloy wheels. The shorter 17mm height keeps the profile compact around the wheel recess, which can help when clearance is limited around the nut pockets.

Fitment caution: Not suitable for radius/ball-seat wheels or flat/washer-seat wheels.
