Tape studs are fastening parts you’ll find in many places on a scooter. They connect two components without a bolt head getting in the way: one side screws into the material, the other side is fastened with a nut. This makes them indispensable in tight spaces or where you regularly disassemble and reassemble a connection. Think of exhaust mounts, the cylinder block, or body panels.
What is a tape stud?
A tape stud is a metal pin threaded on both ends. You screw one end into the base material and secure the other end with a nut. This differs from a regular bolt by having no head; the fastening is integrated into the part itself. It’s useful for parts that you often remove, like during maintenance of the exhaust or cylinder block.
A threaded rod has threading along its entire length and can be cut to size. A tape stud has fixed thread lengths on each side matched to the connection it's intended for. In practice, the terms are sometimes used interchangeably, but for a scooter, it’s smart to check the exact size and thread pitch.
Where do you find tape studs on a scooter?
You’ll find tape studs in various scooter locations:
-
Exhaust mounting to the cylinder block or manifold flange
-
Cylinder head and cylinder block connections with the crankcase
-
Body panels and covers that are disassembled regularly
-
Brake drum and rear axle on certain models
-
Various brackets and engine parts
Particularly for exhaust mounts and cylinder heads, tape studs are common because these connections are regularly undone for maintenance or repair.
Which tape studs do you need?
Choosing the right tape stud depends on three factors: thread size, length, and material.
The thread size must fit the nut and base material. Common scooter sizes are M6, M8, and M10. Always check the original tape stud size you’re replacing, as too coarse or too fine threads can damage the thread hole in the material.
Length is determined by adding the required screwing depth plus the thickness of the part to be fastened, plus the nut height. Ensure enough thread protrudes to fully secure the nut.
Regarding material: steel tape studs are the standard choice for most uses. In high-temperature areas like around the exhaust, choose a version resistant to heat and corrosion. Stainless steel is an option if exposed to moisture or salt, such as scooters stored outdoors year-round.
Replacing a tape stud: what to watch for?
-
Remove the old tape stud using a double nut or special tape stud pliers to avoid damaging the thread hole
-
Check the thread hole for damage or seized threads before installing the new one
-
Apply a small amount of assembly paste or anti-seize on tape studs around the exhaust
-
Tighten the nut with the correct torque; overtightening can damage threads

Frequently asked questions about tape studs for scooters
What’s the difference between a tape stud and a bolt?
A bolt has a head you use to turn and hold it. A tape stud has no head: one end screws into the material itself and the other side is fastened with a nut. This makes tape studs useful where there’s no space for a bolt head.
Which thread size do I need?
Check the original tape stud or thread hole in the part. Common scooter sizes are M6, M8 and M10. When in doubt, measure the outer thread diameter with a caliper.
Can I just replace a tape stud on the exhaust?
Yes, but pay attention to material heat. Use anti-seize or assembly paste on exhaust tape studs and choose a heat-resistant stud. Regular steel studs can seize up when exposed to high temperatures.
How do I remove a seized tape stud?
Use a double nut or tape stud pliers. For rust or heat-seized studs, penetrating oil and gentle turning after short soaking can help. Forcing often leads to a broken stud stuck in the thread hole.
