Reference A8539-21#Ti#Cx0
A8539-21#Ti - TITANIUM threaded through-bolt - Internal diameter 12mm - External diameter 16mm - Depth 21-26mm
Threaded titanium deck bush.
Also known as a through deck fairlead or bush, rope guide and thru-deck bush.
Threaded deck bushes feature two small holes to grip each part with circlip pliers, which then allow the bush to be screwed tight into the surface. This design protects both sides of the surface and accommodates for a range of thicknesses. For extra security, a bonding agent can be used to hold the bush in place.
Typically used to guide a rope or wire through a surface whilst protecting both the rope and the surface from wear.
To install, simply drill a hole to match the external diameter of the bush and then push the bush into the hole. Use a set of circlip pliers to tighten each part into itself.
Titanium deck bushes are strong and ideal for carbon surfaces. Titanium does not react with carbon in the same way Aluminium does. So allow for easy fitting to carbon surfaces without the need for an electrolysis-isolating sealant.
