Sanderson Collector Bolt Set

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/locking nut.

INCLUDES:

• (6) Grade-5 Bolts (1-1/4″ UHL)
• (6) Locking Nuts

TECH TIPS:

Header collector gasket sealing is only as good as a properly secured exhaust system behind 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 be certain to use proper hangers that secure the exhaust piping. This simple task will provide years of trouble-free, accurate sealing.

Do not over-tighten the collector bolts. Having a slight gap between the collector rings is common (see image below). This is why locking nuts are recommended for header collector retention.
