SAE J995

SAE J995 covers the mechanical and chemical requirements for inch series nuts in three grades used in automotive and related industries in sizes to 1-1/2” inclusive. SAE J995 Grades 2, 5, and 8 nuts are readily available in a standard hex pattern.

J995 Tensile Stress Area

Thread, UNC	UNC Stress Area, sq inches	Thread, 8TPI	8 TPI Stress Area, sq inches
1/2-13	0.1419
5/8-11	0.226
3/4-10	0.334
7/8-9	0.462
1-8	0.606	1-8	0.606
1-1/8-7	0.763	1-1/8-8	0.790
1-1/4-7	0.969	1-1/4-8	1.000
1-3/8-6	1.155	1-3/8-8	1.233
1-1/2-6	1.405	1-1/2-8	1.492
To calculate individual nut proofload value, simply multiply the tensile stress area by the appropriate psi proofload value.
