High
80 psi Dynamic overlap shear strength 4,320 min Stainless steel 25°C ASTM D-1002 - To stainless steel, room temperature, 1 in2 (6.45 cm2), jaw speed 0.5 in/min (12.7 mm/min.) Peak force to separate is measured. 72 hour dwell.
1500 (grams) Static shear strength Stainless steel 600,000 sec 22°C ASTM D3654 - To stainless steel, tested at various temperatures and gram loadings. 0.5 in2 (3.22 cm2). Will hold listed weight for 10,000 minutes (approximately 7 days). Conversion: 1500 g/0.5 in2 equals 6.6 lb/in2, 500 g/0.5 in2 = 2.2 lb/in2.
500 (grams) Static shear strength Stainless steel 600,000 sec 66°C ASTM D3654 - To stainless steel, tested at various temperatures and gram loadings. 0.5 in2 (3.22 cm2). Will hold listed weight for 10,000 minutes (approximately 7 days). Conversion: 1500 g/0.5 in2 equals 6.6 lb/in2, 500 g/0.5 in2 = 2.2 lb/in2.
500 (grams) Static shear strength Stainless steel 600,000 sec 93°C ASTM D3654 - To stainless steel, tested at various temperatures and gram loadings. 0.5 in2 (3.22 cm2). Will hold listed weight for 10,000 minutes (approximately 7 days). Conversion: 1500 g/0.5 in2 equals 6.6 lb/in2, 500 g/0.5 in2 = 2.2 lb/in2.
