304 Stainless Steel Rotor Hat Bolt Kit

TTSPORT 304 Stainless Steel Rotor Hat Bolt Kit is service hardware for compatible TTSPORT two-piece performance rotors. The kit is designed for clean thread engagement, corrosion resistance, and proper rotor ring-to-hat assembly when used with the correct bolt size, torque value, tightening pattern, and thread treatment for your specific rotor setup.

Why Rotor Hat Hardware Matters

Rotor hat hardware is small, but it does real work. These fasteners help maintain the clamping force that holds the rotor ring to the hat through repeated heat cycles, vibration, brake dust, road grit, and moisture.

Worn, rusted, stretched, contaminated, or mismatched hardware can make rotor service difficult and may affect the consistency of an otherwise healthy two-piece rotor assembly. This TTSPORT kit is intended for brake builders and owners who want fresh, corrosion-resistant hardware on hand whenever a rotor ring is rotated, replaced, or rebuilt.

Key Features

• 304 stainless steel construction: resists corrosion from brake dust, moisture, and road salt.
• A2-70 strength class: stainless fastener grade used for corrosion-resistant fastening applications.
• Clean thread form: supports consistent torque feel during rotor ring-to-hat assembly.
• Complete hardware service set: includes bolts, nuts, and washers in one kit.
• Service-friendly: intended for rotor ring rotation, rotor ring replacement, or two-piece rotor rebuild work.

Kit Specifications

Always confirm bolt size, length, thread pitch, washer type, nut type, and bolt pattern against your existing rotor hardware before installation.

This product page describes rotor hat hardware only. Rotor rings, rotor hats, bobbins, brake pads, calipers, brake hoses, brake fluid, and complete two-piece rotor assemblies are not included unless separately specified on the final order.

Kit Contents

Use as a complete service set. Do not mix old and new hardware around the same rotor unless the rotor manufacturer specifically allows it.

Installation Notes

• Replace hardware as a complete set to help keep clamping behavior uniform around the rotor.
• Clean the rotor hat and rotor ring mating surfaces before reassembly.
• Remove old thread locker residue, corrosion, brake dust, and debris from the assembly area.
• Follow the torque value and tightening pattern supplied with your specific brake kit or rotor assembly.
• Use the thread treatment specified by your rotor manufacturer, such as dry assembly, thread locker, pre-applied locking compound, or safety wire where required.
• After assembly, verify the rotor sits flat, rotates true, and has no loose hardware before installation on the vehicle.

Compatibility

When to Replace Rotor Hat Hardware

• Replace during rotor ring replacement when the original hardware is stretched, corroded, rounded, contaminated, or heat-damaged.
• Replace if thread engagement feels rough or inconsistent during assembly.
• Replace if old thread locker, galling, corrosion, or damaged threads prevent accurate torque application.
• Replace as a complete set when servicing both rotors for consistent assembly quality.
• Inspect the rotor hat and rotor ring at the same time; new hardware cannot correct damaged mating surfaces.
