A non-sparking aluminium-bronze socket meeting FM and ASTM A342 standards for hazardous-area use
This nonsparking hand socket fits a 3/8 inch drive and engages 3/4 inch SAE fasteners with a 6-point profile. It is made from aluminum bronze and carries FM Approved status to ASTM A342. The unfinished surface suits industrial safety requirements where spark risk must be eliminated.
The FM approval and ASTM A342 listing confirm the alloy meets recognised nonsparking standards for hazardous environments. No impact rating is claimed, so the socket is intended for hand use only. Buyers needing impact-rated drive tools or larger drive sizes will need separate equipment.

Aluminum bronze is softer than steel, so the socket will show wear on the 6-point profile and drive square earlier under heavy use.
The tool is not impact rated, so the drive square or hex walls will deform before any other factor becomes an issue.
