Top Shelf 3/4 Inch Outside Diameter 5/16 Inch Inner Bore 8 Inch Long Mild Steel Seamless Tubes 10 Pack Industrial Spacer Tubing Bolt Compatible Straight Shot For DIY Fabrication Welding Projects Dead Simple Assembly
✔️ 19.05mm O.D. 7.93mm I.D. 203.2mm L. raw steel tube
A set of ten seamless carbon steel rings operates as heavy duty alignment spacers for welding tables, lift mechanisms, and straight mechanical assemblies. The round profile locks fasteners in place while leaving an open channel for cable runs or sliding adapters.
✅ Outside diameter measures 3/4 inch or 19.05 mm across✅ Inner bore fits 5/16 inch or M8 hardware with plenty of clearance
✅ Total length stands at 8 inches or 203.2 mm for rigid setups
✅ Flat milled edges stay square for precise stack height calculations
✅ Low carbon content allows rapid plasma cutting without warping
💡 Why do fabrication teams swap solid dowel pins for continuous hollow tubing in heavy duty fixtures?
Slapping these handy precision sleeves into place clears visual clutter and leaves plenty of access space for wrenches and measuring tools.
- Uniform cross sectional geometry guarantees zero runout when you machine tight bore fits on CNC lathes
- Unalloyed carbon structure accepts spot weld penetration without cracking the heat affected zone during tack runs
- Pre cut stock lengths drop right onto pallet racks or floor mats for immediate grab and go workflow setups
