304 Stainless Steel
Made from true 304 stainless steel, these shims deliver clean, salt-safe, performance that won’t rust, flake, or contaminate your assembly
Ultra thin washer helps eliminate shaft play and reduce vibration.
Fine shimming keeps rods straight and smooth.
Adds precise spacing between worn plates.
Controls gear clearance for quiet rotation.
Thickness tolerance ±0.01 mm lets you stack or single-shim for 0.1 mm steps, so bearings, stages, molds, and carbs stay within spec without re-machining.
De-burred edges slide on without cutting gloves or O-rings; flat lapped faces give full contact for even clamp force and better heat transfer.
Where They Work
• Auto / moto carbs, shocks, starter mounts
• Drone, servo, and stepper motor end-play
• 3-D printer, laser, or optic stage leveling
• Mold and fixture wear take-up
• Electronics heat-path or shield tuning
• Medical, lab, food & pharma hardware
Please note: 304 stainless steel is typically non-magnetic when annealed. Slight magnetic attraction may occur due to cold working during manufacturing. This is normal for genuine 304 stainless steel and does not affect performance.
