Durable for use: Constructed from hardened tempered steel with a lube oil coating to prevent pitting and corrosion.
Made from tight tolerance high carbon steel material used to check spacing and gap widths of dies or any machinery during set-up or repair.
Suitable for designers, engineers, mechanics to measure the thickness of tappet clearances, spark plugs gaps, bearing clearances, piston ring gaps, and other hard-to-reach places.

Specifications:
Measuring range: 0.0015 inch(0.04 mm) ----0.035 inch(0.88 mm)
Material: manganese steel
Blades: 32 pieces
Color: Silver

Package includes:
1 x Feeler gauge

Warm notice:There is some anti-rust oil on the stainless steel feeler gauge to prevent it from rusty, please don't worry about that.
Dust and oil should be removed from the feeler gauge and the workpiece before use.
According to the needs of the size of the part, one or several blades can be inserted into the gap, but to reduce the number of overlapping pieces as far as possible.
Measurement should not be forced into hard to avoid breaking the feeler gauge.
Not suitable for measuring round, spherical, and very high-temperature workpieces.
