Serpent 801555 Impulse Mount Screw Set  [SER801555]

Engine Mount Fasteners You Can Trust

Good hardware keeps your engine stable through rough runs and hard braking. The Serpent 801555 Engine Screws & Washers Set is designed to fit Impulse engine mounts and ships with four M4x12 countersunk screws plus aluminium washers to give a neat, secure joint.

Precision Fit and Lightweight Washers

Screws are produced to exact dimensions so they sit flush with the mount surface, avoiding misalignment. The aluminium washers reduce overall mass while distributing clamp load, which helps preserve mount and engine surfaces under load.

Perfect for Routine Servicing

Whether changing engines or doing routine checks, the Serpent 801555 set is a simple, reliable option to carry in your toolkit. The familiar M4x12 sizing makes swaps quick and repeatable for hobbyists and club racers alike.
