High
90 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.
1000 (grams)	Static shear strength		Stainless steel	604,800 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.
