Titanium Alloy Bleed Bolts for Shimano R8020 R8070 R8170 R9170 – Upgrade from Stripped Hex Standard Shimano Bleed Bolts

Condition: New
Compatibility: Wide range of Shimano road, gravel, and adventure hydraulic STI shifters with M5 bleed port thread (see full list below)

Product Description

Upgrade your Shimano hydraulic brake bleed bolts with these precision-machined Titanium Alloy replacements. If you’ve ever struggled with the factory bolts – the ones where the hex head rounds off after just a few bleeds – this is the permanent fix you’ve been looking for.

Why upgrade?
The original Shimano bleed bolts are made of soft aluminium with a shallow hex socket. Under normal use, they strip easily, leaving you stuck mid-bleed or forcing you to drill out the bolt. Our titanium alloy version solves that problem entirely.

Benefits:

• No more stripped hex heads – Stronger material and precise hex engagement means you can torque confidently without rounding.

• Lightweight titanium alloy – Significantly stronger than soft aluminium, yet still lightweight.

• Corrosion resistant – Won’t rust or seize, even if brake fluid sits around the bolt.

• Direct fit – Same thread and size as original. Replaces your worn or damaged bleed screws in minutes.

Included:

• 2 x Titanium Alloy Bleed Bolts (enough for left + right shifter)

Also fits some earlier Shimano road hydraulic shifters not listed – please check that your original bleed screw uses an M5 thread and 2mm or 2.5mm hex key.

Installation tip: Use a high-quality 2.5mm hex key and light grease on threads. Do not overtighten – titanium bolts require less torque than aluminium.
