*** IN STOCK SHIPS TODAY *** 3/8-24 x 3/8-16 x 1.750" Hemi header stud. This stud is made from heat treated steel that is black oxide coated and has a .500" coarse thread on one end and .750" fine thread on the other with a shoulder for the exhaust header and the blower restraint header bracket. This stud works for any engine that uses 3/8" header studs.
Studs are long enough to be used with blower restraint header brackets but 1.50" should be used on the rest of the header. Overall stud length is 1.90" with a nice fast starter end on the end of the stud for quick between round maintenance.
