ARP has just expanded starter bolts that help with precise bolt length, shank knurl diameter and location, and proper thread engagement. Check out the official release below.

Official Release:

Starter bolts are one of those “taken for granted fasteners” that are actually of critical importance. Key elements include the precise bolt length, shank knurl diameter and location, plus proper thread engagement. Shortcomings in any of these areas can cause excessive noise and lead to starter failure. The engineering and manufacturing teams at industry leader ARP have just added eight new applications for 2016, providing precise mounting for both OEM and aftermarket starters. Important features include smaller diameter, reduced wrenching heads for improved accessibility, precision knurling, and J-form rolled threads for optimum engagement. They are manufactured from Custom 450TM stainless steel material that is rated at 180,000 psi tensile strength—substantially stronger than Grade 8. ARP starter bolts are offered with both hex and 12-point heads. Washers are included as required.

Each ARP starter bolt is polished to a high luster finish for added appeal and is impervious to rust and corrosion. And, like all other ARP fasteners, they are manufactured in-house at the company’s ISO 9001-2008 and AS9100 registered Southern California facilities.
