Review: Excellent for the DIYer, and at a good price. - For the occasional DIYer excellent. Repaired stripped bolts in mu motorbike passenger footrests with no problems. If I had to be slightly critical I'd say the packaging could do with some attention the instruction card is far too small! Review: Better than could have dared to expected. - Used this twice now - once to test and once in anger. Drilled out old M6 thread and retapped using supplied tap. Screwed in the insert and tested with original M6 screw. Result: Unbelievable. Screw threads in nicely, tightens firmer than original (in aluminium) and feels like you could tighten it harder that before. I rarely leave product reviews unless the product is particularly bad or as in this case very impressive. Very satisfied with it's performance - does exactly what it says on the tin (to use a commonly appropriated slogan) and at a good price. ## Features - ALL-IN-ONE 151PC KIT: This highly useful 151-piece thread repair kit is the perfect solution to a damaged or stripped thread hole. - WIDE-RANGING SIZES: Suitable for M5, M6, M8, M10, and M12.
