Why this one
Extended reach for deep clearances
With a 200 mm blade length, this tool stretches into housings, across surface plates, and between components that shorter blades simply cannot span.
Full metric blade range
Blades run from 0.05 mm to 1.0 mm, covering the clearance spectrum you encounter in automotive, marine, and industrial applications.
Built for the professional shop
Weighing 206 g (approximately 7.3 ounces), this tool has enough heft to feel solid in the hand yet stays light enough for all-day carry in a shop apron or machinist tool roll.
Wide application in precision work
Beyond standard spark plug gap checks and valve clearance verification, the 200 mm blade length makes this tool the right choice for surface-plate flatness tests, large-bore piston ring end-gap measurement, and checking alignment shims on rotating equipment.
Accurate thickness measurement you can trust
Consistent blade dimensions let you take repeatable readings across the full 0.05 to 1.0 mm range, so your assemblies meet spec the first time.
Read the full description
Designed for tradespeople who need to measure clearances in deep or wide housings, this Teng Tools long-blade metric measuring tool spans 0.05 mm to 1.0 mm across 200 mm blades. The extended reach lets you check gaps that a standard-length tool cannot access — diesel cylinder liners, large industrial bearings, and surface-plate flatness tests all become straightforward.
Each blade is stamped with its metric value, so you can identify the right thickness instantly. Fan out one blade or combine several to match an intermediate clearance, giving you stepless coverage across the full range. The sturdy pivot holds blades securely when closed and fans them smoothly when open.
At 206 g (roughly 7.3 ounces), the tool balances reach against portability. It fits comfortably in a machinist tool roll, a mechanics cart drawer, or a millwright's carry bag without adding unnecessary bulk.
Use it for valve lash on heavy-duty engines, spark plug electrode gaps on multi-cylinder powerplants, piston ring end-gap verification, shim-stack checks on rotating equipment, and any other task where precise clearance data drives correct assembly. The Teng Tools brand is trusted by professionals worldwide for dependable hand tools, and this long-blade measuring instrument continues that tradition of practical, no-nonsense precision.
