A few extra dollars invested in these tools will really pay off. Ideal for use with resins, solvents, paint, ink, flammable dusts. Non-sparking, non-magnetic, corrosion-resistant tools. Independent tests have shown that our safety tools cannot produce a spark to ignite carbon disulfide, which has the lowest ignition point of any substance. Yet, they have very high tensile strength and hardness. You get maximum torque and shear strength, plus exceptional wear resistance.
