Designed for sterile and critical environment applications, ¼-in. drive stainless steel deep sockets are manufactured entirely from 17-4PH stainless steel, so no chrome plating is required on the surface. The risk of particulate generation and contaminants from exposed ferrous surfaces and deteriorating plating - common with regular industrial carbon steel sockets - is completely eliminated. The new six point sockets are 2 in. in overall length and available in inch sizes from 1/8 in. to 3/8 in. and metric sizes from 4 mm to 10 mm.
