Tough As Nails Copper Flat Washers Metric M18 X 22Mm X 1.5Mm Sealing Rings Heavy Duty Bolt Spacers For Plumbing Repairs Engineering Automotive Diy 10 Pack
✔️ M18 hole, 22 mm span, 1.5 mm depth, matches 0.71x0.86x0.06 inch sizing
This ten pack of copper flat seals spreads bolt pressure evenly to stop flange damage during assembly. Mechanics and hobbyists rely on these robust gaskets for engine builds, pipe fittings, and electrical enclosures where steady load bearing keeps connections tight and leak free.
✅ Annealed copper construction delivers steady thermal conductivity and rust proof longevity✅ Dimensions measure 18 mm center bore, 22 mm outer rim, 1.5 mm face (0.71 inch x 0.86 inch x 0.06 inch)
✅ Polished edges slide cleanly onto standard M18 threaded rods without cross threading risks
✅ Pre cut geometry handles torque loads efficiently while cushioning vibrations on moving parts
💡 What makes copper flat washers handy for dialing in torque specs on beat-up trail gear?
Copper flat seals deliver steady clamping force while stopping unwanted current leaks and thread wear.
- Annealed copper blends flexibility with strength, letting the spacer absorb vibration shock without cracking
- Low electrical resistance improves ground stability on alternators and marine battery terminals
- Soft metal deformation creates a tighter mechanical lock that resists loosening under constant road hum
