ROUND SEAMLESS DOM TUBING
This is the strongest mild steel tubing you can buy. It is used for off-road and racing suspension components and in heavy duty industrial applications. To learn more click red "Round Seamless DOM Tubing" button on left.
STEEL and ALUMINUM
Stop wasting time at the metal yard. We stock a complete line of structural steel and weldable 6061 T6 aluminum. We just got tired of trying to find it in small pieces. Bet you have had the same frustration.
THREADED TUBE
INSERTS 
Whether you call these threaded tube inserts, weld bungs or threaded plugs, we have them. Ours are mild steel and are specially designed to fit our seamless DOM steel tubing. You can turn the shank down in the lathe to fit any tubing size. These can be welded using MIG, TIG or stick.
PORTABLE WELDING TABLE
This mini-welding table can be used to weld, assemble or fabricate. Light enough to move around the shop or carry in the service truck. The top is 12"x15" and is 1/2" thick. The table stands 8" and it weighs only 42 pounds. Great jig table too!
CLAMP for WELDING TABLE
This clamp is specially designed to work with our portable welding table. This one clamp replaces all your welding clamps. The ProtoFab clamp stays attached to the table. It clamps metal combinations that other clamps can't. Available exclusively at this website.
SOCKET HOLDERS
SOFT VISE JAW --
Magnetic! 
Clamp aluminum, brass or wood in any vise with our soft vise jaws. Our special earth magnets last forever. No more shifting vise jaws. We offer 4 1/2" and 6" sizes which fit most vises. All our products are made in the USA.
WELDING FIXTURES 
Another patented product made in the USA. Four welding fixtures to choose. These miter and butt fixtures are better and less expensive than the screw-type weld fixtures.
BUSHINGS, SPACERS, REDUCERS 
We got tired of looking for seamless steel bushings for making shock stand-offs, axle retainers for carts and a variety of bolt through applications. Now you can adapt any hole to fit a 3/8" to 1" bolt or axle.
