13-blade hardened steel feeler gauge set covering 0.03–1.00 mm — for engine valve clearances, spark plug gaps and precision machinery adjustment. In stock in Guwahati.
A feeler gauge set is an essential diagnostic and adjustment tool in any vehicle workshop, engine room or precision maintenance bay. The set's hardened steel blades — each ground to a precise, marked thickness — let you measure tight gaps that no other hand tool can reach: the valve rocker clearance on a diesel engine cylinder head, the running clearance between main bearing shells, the ring gap on a freshly honed cylinder bore. These clearances are specified to the nearest 0.01 mm in service manuals for good reason — too tight and you burn valves or seize bearings; too loose and you get noise, blow-by and rapid wear.
Multi Trade Combines stocks feeler gauge sets alongside the broader Mitutoyo and generic precision measuring range at our AT Road, Guwahati counter. For vehicle workshops servicing commercial vehicles and generators in Northeast India's harsh climate, a durable feeler gauge set that keeps its calibration through repeated use is a daily tool. We supply to automotive workshops, engine overhaul specialists and engineering ITI colleges across Assam and the Northeast.

Diesel generator sets — the backbone of Northeast India's power backup strategy for businesses, hospitals and industrial units — require periodic valve clearance checks and adjustment. Under-torquing or misadjusting valve clearances without a calibrated feeler gauge leads to poor combustion, hard starting and eventually burnt valve faces. Multi Trade Combines also stocks the related tools: outside micrometers for bore and journal measurement, vernier calipers for part-to-part dimensional checking, and dial gauges for shaft run-out and end-float measurement. The feeler gauge set pairs naturally with these instruments to give a complete engine-measurement toolkit. Genuine hardened-steel sets that stay flat and hold thickness over years of use — that is what we stock and supply.

A feeler gauge set is used to check clearances that must be held within close tolerances: valve clearance (tappet gap) on petrol and diesel engines, spark plug electrode gap, contact-breaker points gap on older ignition systems, connecting rod big-end bearing clearance, and piston ring end gap. The thin calibrated blades are slid into the gap until the correct blade thickness produces the specified light drag. Call +91 91812 13332 for current stock.
A standard 13-blade set typically covers 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.10 mm, 0.15 mm, 0.20 mm, 0.25 mm, 0.30 mm, 0.40 mm and 1.00 mm — covering the most common engine and machinery clearances.
