Ampco 3/4" Drive 30 mm 6-Point Hand Socket

Ampco 3/4" Drive 30 mm Socket

The Ampco SS-3/4D30MM is a 30 mm metric hand socket with a 3/4 inch square drive and six-point output. Its aluminum-bronze construction makes it nonsparking, non-magnetic and corrosion resistant. It meets US government requirements defined by MIL-I-17214 and is Factory Mutual approved for hazardous environments. This tool suits maintenance crews in refineries, chemical plants and mining operations where ignition risk must be eliminated.

Installation and common issues

The socket fits directly onto any 3/4 inch drive ratchet or breaker bar without adapters. Standard depth allows access to typical fastener lengths in tight assemblies. Because the material is softer than hardened steel, applying excessive torque can round the hex or deform the drive square. Users should verify that the fastener is free of rust and debris before engaging to avoid premature wear.

Capacity and headroom

The 30 mm hex opening handles standard metric fasteners found on heavy equipment flange bolts and valve packing glands. Six-point geometry distributes load across flats, reducing the chance of rounding compared with twelve-point designs. The socket is not intended for impact-gun use; repeated hammer blows will mushroom the drive end and compromise the nonsparking properties. For larger diameters or higher torque demands, a different socket size is required.
