NAS1304-11.

NAS1304-11

All NAS11XX/62XX, NAS13XX/66XX and NAS 63XX series hexbolts are 160,000 PSI minimum tensile and 95,000 PSI minimum shear strength fasteners.

NAS 11XX/62XX/13XX/ 66XX series are alloy steel rated for 450 degrees F maximum temperature.

NAS 63XX series are A286 stainless rated for 1200 degrees F maximum temperature.

To calculate actual capacities of a given sized fastener see the tech info section on our website.

All bolts in the above series are designated by grip length: the grip length is the full diameter unthreaded portion of the bolt beneath the head. Grips run in 1/16 (.0625) increments; dash number is grip in sixteenths. Adding thread length (constant for all bolts within a given diameter and series) to grip length yields the overall length (L) of the bolt (bottom of head to end of threads). Bolts with heads drilled for safety wire have an H prefix or suffix to the grip length (NAS1303-10H; NAS6603H10)

Listed below are hex head sizes and thread lengths for all bolts within a given series.

Please ensure thread length is adequate to accommodate the locknut you desire to use.

NAS 11XX/62XX AND 63XX SERIES BOLTS SHOULD NOT BE USED IN TENSILE APPLICATIONS AS THREAD LENGTH IS INSUFFICIENT TO ENSURE ADEQUATE CLAMPING STRENGTH.

PLEASE CONTACT US IF ANYTHING IS UNCLEAR OR IF YOU REQUIRE ASSISTANCE.

NAS 1304 & 6604 bolts. Size: 1/4-28; hex head size: 7/16. Thread lengths: 1304/6604=.425
