M12 x 1.25, 60° Taper, Star D20

This is an M12 x 1.25 wheel bolt with a 60° conical seat, using a Star D20 drive. This drive format is typically chosen for wheels that need an internal-drive style fastener (for example, when the wheel recess design makes standard external hex access less convenient).

Multiple thread lengths are offered, which is essential for matching the bolt to different hub/wheel thicknesses and spacer combinations.

Design Features

Star/internal drive wheel bolts are commonly selected when:

• The wheel has deep or narrow bolt recesses
• The user wants an internal-drive style head rather than a traditional external hex
• There is a desire to reduce the chance of rounding external hex corners in tight pockets (general industry rationale)

Common Applications

• Wheels requiring M12 x 1.25 wheel bolts with a 60° conical seat
• Aftermarket wheels using internal-drive style bolts (fitment dependent)
