The table below lists by size the Tensile Strength, Proof Loads and Clamp Loads appropriate for use with the L9® Fastening System. Recommended torque values to achieve the recommended clamp loads are also shown, for applying torque to the bolt head or to the nut. Notes below show how the loads are calculated. Refer to “User Cautions” prior to installation of L9® fasteners.

Dimensions show below apply to L9® Fastening System components. Dimensions shown are the same for both UNRC Unified National Coarse and UNRF Unified National Fine thread prod-ucts.Washersarethesameforboththreadtypes.

All Items Phosphate & OilCrest flange bolts and locknuts form a strong and dependable fastening system that substantially cuts truck assembly, maintenance and repair costs. The flange bolts are made of IFI111 industry stan-dard specs, and when used in conjunction with the flange locknuts form a 150,000 PSI tensile strength fastening system equivalent to SAE J429, Gd 8 industry standard specification. Flat washers and lock washers are not needed with the flange bolts. Also our flange fastening system reduces the need for costly hole preparations such as deburring and countersinking.Product Specifications: Flange Screw Screw MinimumProduct & Nut & Nut Head Nut Screw ThreadDiameter Diameter AcrossFlats Height Height Length3/8” .780”/.810” .551”/.562” .370”/.390” .415”/.425” 1”1/2” 1.031”/1.070” .736”/.750” .490”/.510” .545”/.555” 1-1/45/8” 1.300”/1.330” .922”/.937” .600”/.620” .680”/.690” 1-1/23/4” 1.510”/1.565” 1.110”/1.125” .710”/.730” .740”/.750” 1-3/4
