Product Details
✓40 PIECES, 4 THICKNESSES: 10 each of 0.1mm, 0.2mm, 0.3mm and 0.5mm. Stack them to reach any gap from 0.1mm up to 1.1mm in 0.1mm steps, so one kit covers the full adjustment range instead of ordering a single size and hoping it fits.
✓EXACT 13 x 20 mm SIZE: 13mm inner diameter, 20mm outer diameter. The 13mm bore clears both M12 metric and 1/2 in imperial bolts, so one kit covers both. Measure before ordering, this listing is the 13x20mm size only.
✓STAINLESS STEEL THROUGHOUT: corrosion resistant material, not plated mild steel. Holds up in gearboxes, engine bays and humid workshops without rusting or staining the parts it sits against.
✓DEBURRED AND FLAT: tight tolerance shim washers with clean, deburred faces that sit flush instead of cocking the part. For bearing preload, end float, pulley alignment and squaring up assemblies where a flat washer is too thick.
✓BEARING, SPACER AND MACHINE WORK: bearing preload on 13mm shafts, M12 and 1/2 in bolt spacing, gearbox and CNC setup, pulley and coupling alignment, plus general machine and linkage packing.
