Facom 804.L Feeler Gauge, 19 Blades

A feeler gauge is a hand-held measuring tool used to measure the size of small gaps between two objects that are in close proximity. The tool has a number of folding metal strips (also known as blades or leaves) which are machined to specified thickness levels. A feeler gauge can be used to gauge a multitude of narrow slots to check that mechanical parts are in safe working order.

300-6556 - 804.L - extra-long round tip - blade length 150 mm, range 4/100 mm – 25/100 mm, weight 100g

300-6562 – 804.P - standard length pointed tips – blade length 90 mm, range 4/100 mm – 100/100 mm

300-9971 – 804 - standard length round tips – blade length 90 mm, weight 60g, range 4/100 mm – 100/100 mm

The feeler gauges are in metric units

Available in calibrated versions

They are used to measure gap widths and to precisely determine the size of the small gap between the two parts.

They can be either imperial units or metric measurements.

Imperial units typically measured in thousandths of an inch and metric in hundredths of a millimetre.

Can be used for checking: tappet clearances, spark plug gaps, distributor points, bearing clearances and piston ring gaps.
