AND USAGE LIMITATIONS: THESE NUTS ARE INTENDED FOR SHEAR APPLICATIONS.
THE STEEL NUTS ARE DESIGNED TO DEVELOP AN ULTIMATE LIMITATIONS:
TENSILE STRESS (Ftu) OF 70 KSI: THE ALUMINUM NUTS ARE DESIGNED
TO DEVELOP AN ULTIMATE TENSILE STRESS (Ftu) OF 70 KSI FOR SIZES
-04 THRU -03 AND 35 KSI FOR SIZES -4 AND LARGER. THE CRES NUTS
ARE DESIGNED TO DEVELOP AN ULTIMATE TENSILE STRESS (Ftu) OF
70 KSI FOR SIZES -04 THRU -8 AND 58 KSI AND LARGER: AND COPPER
BASE ALLOY NUTS HAVE NO AXIAL STRENGTH REQUIREMENTS. THESE ULTIMATE
TENSILE STRESS REQUIREMENTS ARE BASED UPON THE CROSS SECTIONAL
AREA AT THE MINIMUM MINOR DIAMETER OF MIL-S-8879 EXTERNAL THREADS,
AND WILL BE OBTAINED WHEN THE NUTS ARE TESTED ON BOLTS HAVING
A MINIMUM ULTIMATE TENSILE STRENGTH OF 160,000 PSI. THESE NUTS
ARE DESIGNED TO BE USED ON 3A EXTERNAL THREADS. THESE NUTS SHALL
BE USED IN ACCORDANCE WITH THE LIMITATIONS OF MS33588. |
