73 Seat Bolts
Of the 4 seat mounting bolts, should there be one or two bolts with the sharp end? If only one, where does it go?
Thanks!

Re: 73 Seat Bolts
Earlier cars had pointed bolts with captive washer at all four corners. SEMS is one headstamp used for seat mounting bolts in 70.
Pointed, self-tapping bolts or screws are generally used for applications with body bolting plates; the point allows the fastener to be quickly and easily piloted into a smaller predrilled hole in the bolting plate and threads cut as the fastener is torqued. Other styles of self-tapping machine screws may only be tapered slightly on the end and not fully pointed; the taper is enough for the screw lead to engage the bolting plate material.
Do your non-pointed bolts have headstamps?...If so, what are they?Last edited by Chuck S.; March 19, 2010, 07:20 AM. -

I've never seen a self-tapping/thread-cutting bolt used for seat attachment; that style of bolt is only used in plain, unthreaded holes. Seat bolt anchor plates have machine-threaded holes or weld-nuts to accept straight machine-threaded bolts (at least they did when they left St. Louis).Comment

No self-tapping ones here either, but I have seen the pointed tips most of the time.
