Auto-plaza Titanium M4 x 26mm Disc Brake Caliper Bolts — 4 Sets with Shimano Clips, Lightweight Corrosion-Resistant

These are Auto-plaza titanium alloy M4x26mm disc brake caliper bolts (4 sets) designed to replace threaded Shimano caliper fasteners with lightweight, corrosion-resistant hardware.

If your bike uses a threaded caliper mount and you need durable, light-weight replacement bolts, these titanium M4x26mm screws from Auto-plaza are built for that purpose. Each package contains four complete sets (enough for two calipers on most bikes) and includes the clips used with Shimano-style assemblies. The bolts match OE reference Y8J798060 and are intended strictly for threaded mounting points—do not use them on unthreaded posts or adapters.

Will these bolts fit my Shimano disc brake caliper?

They are specifically made to be compatible with Shimano calipers that accept M4 threaded fasteners. Check that your original mounting bolts are M4 and 26 mm long and that the caliper uses threads rather than a smooth post.

• Bolt size: M4 x 26 mm — measure your original fastener to confirm.
• OE reference: Y8J798060 — helpful for cross-checking parts lists.
• Includes clips as used in Shimano-style caliper fitments.

How will titanium bolts change my bike's performance and maintenance?

Titanium hardware reduces weight and offers high strength with excellent corrosion resistance compared with standard steel bolts. They won’t alter braking function but can lower unsprung weight slightly and resist seizing in wet conditions, making future removal easier.

• Lightweight alloy reduces small-item mass without compromising clamping strength.
• Corrosion resistance cuts down on seized fasteners in humid or salty environments.
• High hardness and durability maintain secure caliper mounting under riding loads.

What should I know about installation and compatibility limits?

Installation is straightforward for mechanics familiar with disc brakes, but these bolts must only be used where a threaded hole is present. Avoid using them on non-threaded posts or with adapters that rely on different fastener profiles.

• Only for threaded caliper mounts—do not press into smooth posts.
• Tighten to your brake manufacturer's torque specification to avoid stripping threads.
• Use anti-seize or threadlocker per your service practice, depending on preference.

What comes in the package and how many bolts do I get?

Each package contains four complete sets of bolts and clips—sufficient for most rear and front caliper replacements on single bikes. The clip design matches Shimano assemblies so you can reuse existing hardware or replace it entirely.

• Quantity: 4 sets per package — includes bolts and the required clips.
• Screw specification: M4 x 26 mm — confirm against original hardware.
• Material: titanium alloy for long-term durability and light weight.

Who is this for: Riders, bike shops, and home mechanics who want lightweight, corrosion-resistant replacement caliper bolts for Shimano-style disc brakes with threaded mounts. These bolts suit commuting, gravel, and road cyclists who prefer durable hardware that resists seizing, and technicians replacing worn or corroded fasteners. If your caliper uses non-threaded posts or a different bolt size, choose the correct specification instead.
