OVERVIEW

Keep Your Equipment Tight and Right

When you are in the middle of a heavy fabrication job, the last thing you need is a piece of equipment failing due to a loose or missing bolt. The Tweco 351505 Hex Head Cap Screw is the exact replacement part you need to get your gear back in fighting shape. Sized at 1/2"-13 with a 1-3/4" length, this heavy-duty screw is the backbone of many connections found in professional welding setups, from securing heavy ground cables to bolting down machine components.

Why bother with a specific part number for a screw? Because fit and finish matter. In welding, equipment is subjected to constant abuse—heat, sparks, drops, and vibration. A generic bolt might not have the right tensile strength or the exact thread tolerance needed to stay put. This Tweco OEM screw is built to handle the shop environment. The hex head allows you to really crank down on it with a wrench, ensuring that whatever you are fastening stays fastened. This is especially critical for electrical connections; a loose connection isn't just annoying, it creates resistance that generates heat, melts cables, and ruins your arc stability.

Maintenance is part of the welder's life. Checking your ground clamps, cable lugs, and machine casing for loose hardware should be part of your routine. If you find a stripped thread or a sheared head, replacing it immediately with the Tweco 351505 saves you from bigger headaches down the road. Don't let a fifty-cent problem turn into a five-hundred-dollar repair. Keep your shop stocked with the right hardware so you can fix it fast and get back to burning wire.

Ideal for:

  • Replacing stripped or lost bolts on heavy-duty ground clamps.
  • Securing cable lugs to power sources.
  • General equipment repair where a 1/2"-13 x 1-3/4" bolt is specified.
  • Restoring Tweco equipment to factory condition.
