Sanderson high tensile Grade 5 alloy header collector bolt set resists loosening caused by thermal expansion and contraction.
Aircraft grade locking nuts stay tighter and secure for much longer than conventional spring steel lock washers.
A perfect addition to Sanderson headers and Sanderson Copper Collector Gaskets.
NOTE: Also available as a single bolt/nut.
- (6) Grade-5 Bolts (1-1/4″ UHL)
- (6) Locking Nuts
TECH TIP :
Header collector gasket sealing is only good as a properly secured exhaust system after the headers. If the exhaust piping and mufflers are swaying back and forth with every motion of the vehicle it can strain the sealing accuracy of the collector gaskets and header flanges. Please use proper hangers that secure the exhaust piping. This simple task will provide years of trouble-free, accurate sealing.
