Automotive Racing Products, ARP, has grown its selection of “bulk” metric bolts to cover sizes from very tiny M6 with a 12mm underhead length to a large M12 x 100mmn UHL offering. The M6 bolts are made with a 1.00 pitch count, the M8 fasteners have a 1.25 count, M10s come in both 1.25 and 1.50 pitch and M12 bolts are available with 1.50 and 1.75 pitch counts. All are available in polished stainless steel or black oxide finished 8740 chrome-moly and both are rated at 170,000 psi tensile strength—substantially higher than ISO 8.8 or 10.9 specifications. Furthermore, ARP offers them with either hex or 12-point heads. ARP’s proprietary stainless-steel alloy is impervious to rust and corrosion and it won’t chip or peel like ordinary chrome plated bolts. They’re perfect for dressing up engine compartments, protecting chassis and suspension components from the elements, and a multitude of other applications. They come skin packed in handy 5-packs, as do a full lineup of SAE coarse and fine bolts. A complete listing of specifications, including grip length, wrenching size, collar diameter, etc. can be found in ARP’s 2017 catalog by clicking the Link at the top of this page.
