I have used these for years but couldnt find replace ments for old ones I had. After years of use my old ones were wearing so the were not accurate anymore and the hardware store I bought them at no longer carries them. These appear identical I gapped a plug for my SR500 and checked the gap with feeler gauges and it was spot on.
Simple, effective, cheap, weighs nothing and fits in any tool kit.
The center of the gap gauge is blank.
