Crankset cover screws are tiny parts that do a lot of visible work: they keep the crank cover secure and clean up the look around the crank interface. Our aluminum multicolor crankset cover screws are an easy swap when you want a fresher finish, a matched color theme, or simply a spare set on hand for maintenance days—without adding bulk to the bike. For more guidance, see Aluminum Alloy Crank Arm Fixing Bolt & Cover Screw Set.
Even though they’re small, these screws sit in a high-visibility spot on the drivetrain side. When they’re the right size and properly installed, they quietly improve both protection and presentation. For further reading, see Bicycle Stem Top Cap 31.8mm – Aluminum Alloy Headset ….
Our team sees aluminum fasteners chosen most often for practical, visible upgrades—light, corrosion resistant, and available in finishes that let you personalize a build without committing to major component swaps.
Crank covers and caps vary by brand, model, and crank standard, so compatibility comes down to matching the original hardware—not guessing by bike type alone (MTB vs. road).
| Check | What to look for | Why it matters |
|---|---|---|
| Thread size/pitch | Matches the original screw exactly | Prevents cross-threading and ensures proper hold |
| Length | Same as original (or verified safe alternative) | Avoids bottoming out or weak engagement |
| Head/tool type | Hex/Torx and head profile match your access | Reduces stripping and makes torque control easier |
| Cover seating | Cover sits flat with no rocking | Protects the interface and avoids rattles |
| Thread condition | Clean threads; replace damaged screws | Improves holding power and serviceability |
Multicolor hardware works best when it looks intentional. Decide up front whether you want the crank area to “disappear” or become an accent point.
Small fasteners are easy to overtighten and easy to strip, so the “clean” install is the one done patiently.
For general best practices on handling threaded fasteners, we like Park Tool’s repair guidance (Park Tool — Repair Help). And when you want model-specific documentation, Shimano’s service instructions are a dependable reference (Shimano — Service Instructions).
Fit depends on your crank cover design and the exact thread size/pitch and length. The safest approach is to match one of your existing screws directly or confirm the specifications in your crank/cover documentation before you order.
They should be secure and snug, not cranked down with excessive force. If your crank or cover specifies a torque value, use that spec and tighten evenly with the correct tool to avoid stripping.
Use the exact bit size, seat it fully, and apply firm pressure so the tool doesn’t cam-out and scratch the head. Start threads by hand and stop at snug to avoid the slips and scuffs that usually come from mismatched tools or over-torque.
