The faces and head are made of aluminum-bronze that is Factory Mutual approved, so these tools inhibit sparking, resist corrosion, and are nonmagnetic. They satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. All are suitable for driving chisels and striking work without damaging its surface. To avoid marring the workpiece, use these mallets on material that is harder than the metal faces. Lighter weight mallets are good for tapping work into place and driving a chisel to make small cuts. Use heavier weight mallets when assembling joints, dislodging stuck parts, and making aggressive cuts with a chisel. A textured grip provides slip resistance. For replacement handles, see Fiberglass Hammer Handles.

Warning: Do not use these tools in direct contact with acetylene.
