Industry-leading high performance fastener manufacturer ARP has added new part numbers to its already sizeable selection of “bulk” bolts that come in convenient 5-packs. The additions expanded the selection of 7/16-20 bolts from as short as 0.500″ to an underhead length of 6.000″. These bolts are offered in polished stainless steel or black oxide finished 8740 chrome moly, both of which are rated at 180,000 psi tensile strength—considerably stronger than Grade 8 hardware. They are also available with a choice of 12-point or hex heads. Designed to augment ARP’s huge selection of fastener kits for specific applications, bolts from as small as #10-32 and #10-24 to as large as ½” diameter (or M6 to M12) can be employed in a variety of engine, drivetrain and suspension applications. They are available in SAE coarse and fine thread, plus Metric in varying pitches. For more info, contact ARP. 800.826.3045, www.arp-bolts.com.
