Silverline Feeler Gauge 13 Leaves (0.05 – 1.0mm) (793828)

There's not much that can be said about them - they're feeler gauges, very accurate (yes, I am anal enough to have checked them with a micrometer), and about half the price I've ever seen them anywhere else. They've stood up to two guitar setups and my mate using them to check and shim the valves on his car's engine.Don't clean all of the oil off though - they're not stainless steel, and if they do get some surface corrosion and you're absolutely reliant on accuracy this can throw it off by a crucial fraction of a millimetre. If you're using them for non-engineering applications that you don't want to leave oil over (like guitar setups), clean them off but then re-apply a light oil to keep them clean.

Arrived quickly and does the job

Very handy. A little oily in its packaging, but that nothing a quick wipe won't fix. Seems to be pretty good quality.

Used to measure spark plugs etc. Come oiled before hand, good or bad depending on use, bad for me as I didn't want to contaminate the spark plugs and thus the engine. Great if you want to prevent rust and wear. Only takes 30 seconds to wipe down the ones you need. Good material quality. Step sizes are good, and perfect .7 and .6 for sparks.

These feeler gauges have been a great addition to the tool box, use them for setting preload on rocker arms and general tolerancing during engine building and no complaints, holding up well so far, well worth the money in my opinion

cheap item but the quality doesn't reflect the price. its been used quite roughly for a couple months now and still going strong, just need to keep oiling every so often to keep them easily movable

This thing comes covered in oil, which depending on your use can be a good thing or a bad thing. For me it's an awful thing as I intend to use this to setup guitars at home. I've wiped as much off as I can with a microfiber cloth but it still leaves oily skin when handling it.Also, some of the markings on the blades look partially worn off. Hopefully they won't get worse as they look printed on, so if they wear off, you'll need a vernier to know what blade you're using!

Good value, but as someone else wrote...if wanted for guitar set up you need to wipe off a hell of a lot of oil. Can't complain though... Set string height perfectly.
