Nonsparking Pin Removal Punches

Made of materials that are Factory Mutual approved, these nonmagnetic, corrosion-resistant tools inhibit sparking. Use them to knock out pins and rivets that have already been loosened. They satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. Nonsparking tools are not, however, classified as antistatic because they do conduct electricity.

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

Nonsparking Alignment Pins

Made from aluminum bronze that is Factory Mutual approved, these nonmagnetic, corrosion-resistant pins inhibit sparking. They satisfy OSHA requirements for nonsparking tools for locations where flammable vapors and combustible residues are present. Nonsparking tools are not, however, classified as antistatic because they do conduct electricity. Use alignment pins to align structural components such as I-beams and angle irons for bolting, riveting, and welding.

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

Nonsparking Center Punches

Made of aluminum-bronze that is Factory Mutual approved, these nonmagnetic, corrosion-resistant tools inhibit sparking. Also known as marking punches, strike these with a hammer to mark hole centers in metal and other materials. Use before drilling to prevent your drill bit from wandering when starting a hole.

They satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. Nonsparking tools are not, however, classified as antistatic because they do conduct electricity.

Note: Do not use these tools in direct contact with acetylene due to the possible risk of explosion.

Mold and Die Bushings

Guide pins, punches, and other components in molds and stamping dies—these bushings help you align the upper and lower halves of your setup. An external channel directs lubricant into these bushings, so you don’t need to line up your nozzle with the lubrication hole. Once the lubricant is inside, a figure-eight-shaped groove distributes it evenly along the surface.

Self-Lubricating Mold and Die Bushings

Graphite plugs in these bushings help pins, punches, and other components slide through molds and dies without the mess of grease or oil. These bushings keep the upper and lower halves of your setup aligned. Made from aluminum-bronze, they can handle the high loads and repeat motion of production lines.

Ejector Pin Bushings

Eject parts smoothly from your mold. These bushings reduce friction between your ejector pins and plates, so they slide easily and wear out slowly. An external channel directs lubricant into these bushings, so you don’t need to line up your nozzle with the lubrication hole. Once the lubricant is inside, a figure-eight-shaped groove distributes it evenly along the surface.
