These 1/2" drive metric sockets loosen and tighten fasteners in hygienic and sanitary applications. They hold plastic inserts that prevent metal contact between the socket and fastener head to avoid contact corrosion.

Plastic inserts are manually pressed into hygienic sockets to protect fastener heads and avoid metal-on-metal contact when tightening or loosening fasteners. These FDA-approved inserts help prevent contamination and contact corrosion in sanitary and washdown environments.
