No more problems with the self-loosening of Downpipes: Ford´s OEM loader-screws are very problematic. They often loosen, especially after being dismounted once. If the problem of the self-loosening screws will not be recognized immediately, the worst consequence can be a catalyst damage. This in turn can result in a major engine damage.
The extra strong and heat-resistant HD-screws are provided with an additional mechanical protection, which makes it impossible to loosen the screws while driving.
We recommend using these screws in combination with our Upgrade-Seals: - Flange seal Focus 76mm 3" exhaust systems/Downpipes (Art.-Nr. HGFFAGADPFD76) - Focus 2 RS/ST stainless steel Downpipe-Y-Pipe-Seal (Upper part) (Art.-Nr. HGFFDPT76)
