Installation Method

Punch or drill specified hole size. Ensure that you are using the correct gauge fastener for the panel thickness used. Place part in anvil and locate panel hole over spigot.

Using a profiled punch, ensuring panel is held perpendicular to the punch and anvil face, apply a parallel squeezing force to form the correct spigot profile.

Alternatively, a domed anvil or a ball bearing and hammer can be used to form the spigot profile, however this will not give optimum performance.

For optimum performance, installing with a profiled punch is highly recommended. A flat punch can also be used but will result in reduced push-out performance.

Performance

All performance figures are averages obtained over a range of installations for steel parts in mild steel panels and should be used for guidance only. Fastener material, panel material, hole preparation, installation tooling and method can affect part performance. Actual in-use torque to turn resistance increases with clamping load. We always recommend that you carry out your own tests in the actual application. Please call our sales team and we will be happy to provide you with samples as well as offering technical assistance.

Info

Tank Bush Closed End Rivet Bushes provide strong reusable captivated sealed threads for thin panels. They can be installed into panels as thin as 0.5mm and do not suffer from the maximum hardness or centreline to edge limitations of self-clinching nuts so are suitable for installation into panels of any hardness such as hard stainless steels or in close to edge applications. Featuring an undercut shoulder to provide a sharp skirt to help seal the fastener at the panel face, this style of rivet bush offers good torque to turn resistance while maximising spigot strength to resist push-out. Manufactured to suit a specific panel thickness, we can manufacture parts with custom dimensions to suit your particular application. Available from stock in metric thread sizes in steel, electro zinc plated steel and stainless steel. We can also supply Unified, BA, BSW and BSP thread sizes subject to minimum order quantities. 316 stainless steel, aluminium and brass tank rivet bushes are available to order subject to minimum order quantities. Ideally tank rivet bushes should be installed using a press with a suitability profiled punch by applying a parallel squeezing force, however they can be installed using a hammer and ball bearing to form the spigot profile.
