Our Honda K20 K24 M-series M12 Extreme Power head studs are made from the Highest-Grade Super Alloy that have gone through rigorous heat treatment and testing. With a minimum tensile strength of 260kpsi, these are not prone to hydrogen embrittlement like the L19/H11 material and can be handled without worrying about failures. We use a True-beam design all the way through the length of the stud resulting in better clamping force and torque values (it's not necked-down or undercut like others). "Only settle for the Best!"

The kit includes: Studs, nuts, washers, lube, and instructions.

- Engine block must be re-threaded to accept the larger M12 stud using our custom M11 to M12 transition tap kit (sold separately).

- No modification is necessary with the K-series cylinder head (use with stock OEM dowel pins).

Good option for FSD drivers with a thin skin
Color: Black
Works great. Holds the phone very well and can be repositioned very quickly to accommodate various driving modes like laid back and deep or focus edge of your seat with getting yelled at by FSD (not really self driving)

'A Must Buy'....!!
Color: Black
I have had multiple Magnetic phone mounts, this is by far the best one yet. For the price, it is a 'must' buy, it fits perfectly on corner of screen, very tight, never an issue with bumpy roads, sharp curves, etc. You can use mount at different angles, whatever suits your needs.
