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.

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
Nuts ×20
Matching nuts for rotor hat and rotor ring assembly where the TTSPORT rotor design uses this hardware format.
Washers ×20
Matching washers supplied as part of the service hardware set.
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.
Important: Rotor hat hardware is safety-critical. If you are unsure about torque spec, bolt length, thread pitch, washer stack, locking method, or compatibility, consult TTSPORT or a qualified brake technician before driving.
Compatibility
This hardware kit is designed for compatible TTSPORT two-piece rotor assemblies. It is not a universal rotor hardware kit. Bolt diameter, bolt length, thread pitch, nut type, washer style, rotor hat thickness, rotor ring thickness, and bolt-circle pattern must match the rotor assembly exactly.
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.
Frequently Asked Questions
What is included in the kit?
The kit includes 20 bolts, 20 nuts, and 20 washers in 304 stainless steel. It is intended as service hardware for compatible TTSPORT two-piece rotor assemblies.
Will this fit any two-piece rotor?
No. It is designed for compatible TTSPORT two-piece rotor assemblies. Always confirm bolt diameter, length, thread pitch, washer type, nut type, and bolt pattern against your current hardware before installation.
Why 304 stainless instead of plated steel?
304 stainless steel resists corrosion from brake dust, moisture, and road salt, which helps keep threads cleaner and makes future rotor service easier.
What torque should I use?
Always follow the torque value and tightening pattern provided with your specific brake kit or rotor assembly documentation. Do not guess torque values for rotor hat hardware.
Do I need to replace hat hardware every time I change rotor rings?
We recommend replacing the hardware during rotor ring service if the old fasteners are stretched, corroded, contaminated, rounded, or covered with old thread locker. Fresh hardware helps support consistent assembly quality.
Need help confirming rotor hardware fitment?
Send your rotor model, rotor hat photos, current bolt dimensions, thread pitch, bolt count, and rotor assembly details. TTSPORT will help confirm whether this hardware kit matches your two-piece rotor setup.

Superb!
Style: Original
My dog absolutely loves this ball. It's too big for him to fit all the way in his mouth, so it's held up pretty well and still makes the sounds.

Durable, Rugged, Dog Approved Fun!!
Style: Original, Style: Original
This thing is durable and worth every penny! I bought this over 5 years ago for my rescue and he STILL loves it. He plays with it near daily and it's got a LOT of love-work scrapes, scratches, and scuffs. But it still works perfectly!! Because he's on the medium side, he can't quite bite down on it. Not sure how it'd hold up to heavy chewers with larger mouths. But he can play with this solo for ages and has SO MUCH fun. We love to listen to his "conversations" as he gets into it with this ball. It's been a winner since the day we took it out of the box. It's also the longest lasting toy we still have! Everything else either wore out, was destroyed, or broke. This battery-free ball has made the cut for us.

Lasted a day for my dog
Style: Original, Style: Original
My dog absolutely loved this toy, but sadly it didn’t even last a full day 😩 I’m not sure if that’s because I have a Rottweiler/Lab mix with the jaw strength of a tiny excavator, or if the durability just isn’t great. Within a few hours, he had already torn right through it 🥲 That said, the sound it makes had us cracking up and definitely kept my dog entertained and intrigued while it lasted!

Great toy!!!
Style: Original
My dog went mental over this ball!!! She will let me roll it through the backyard or in the house and she will go nuts for it but the great part, she will play by herself with this ball. She will roll it and jump on it and just have a blast.
Since this is not a normal chew toy, my dog's big, she only gets it when I'm with her. It kind of makes it our special thing when I pull it out. We play every day with it and her enthusiasm has never lessened. She can be in another room when I take it out of the cabinet and the second she hears it, she will run into walls in her rush to get to me so we can play! It really is better than just throwing a ball back and forth. She's completely engaged the entire time it's out.
I highly recommend it but just know it's not a normal toy that you can just throw to your dog and walk away. It is an amazing toy to help you bond with your pet.
