NAS BOLTS
NAS 11 AND NAS 13 SERIES CLOSE TOLERANCE BOLTS These National Aerospace Standard, fine threaded, dimple-head hex bolts have a minimum tensile strength of 160,000 psi and a minimum shear strength of 95,000 psi. Thread length is consistent within each diameter (11 series has a shorter thread), and grip lengths are available in 1/16” increments. Used in applications where a premium quality, high strength bolt is necessary.
