ARP, a leader in the fastener manufacturing industry, has officially expanded its offerings of premium quality polished stainless steel bolts, making it easier than ever to upgrade factory hardware. These new products are available in convenient 5-packs, enabling users to acquire the specific sizes they need.
The latest additions to the “Tiny Bolt” lineup include various sizes ranging from larger bolts of 1/2” to 1/4” in diameter, as well as the introduction of the new #8-32 size, alongside existing sizes like #10-32 and #10-24. These #8-32 bolts, manufactured in-house at ARP’s California facilities, are designed with 12-point heads and come in a wide range of underhead lengths: .375”, .500”, .625”, .750”, .875”, 1.000”, 1.125”, 1.250”, 1.375”, and 1.500”. This versatility makes them suitable for various applications within a vehicle’s engine compartment, interior, and more.
All ARP accessory fasteners, whether polished stainless steel or black oxide finished 8740 chrome moly, are nominally rated at 180,000 psi tensile strength—20% stronger than traditional Grade 8 hardware. The stainless steel options also offer the added advantage of being virtually impervious to the elements, ensuring durability and longevity.
