Very effective on the adjustment screws on a watch strap

Bought this to use as spoke prep for a bicycle wheel build. This product is essentially bike spoke lubricant and is much cheaper than ParkTool spoke prep. It allows for screws to be adjusted while also reducing nuts from coming loose.

I wish I knew this product existed a couple of years ago. I have been using the blue Loctite on my RC cars and often times fine that the blue still has too much holding strength for small fasteners. This purple formula works absolutely perfect on M3 and M4 set screws that do not require a more permanent fastening solution That you often get from the blue or red. I find the purple Loctite product to be superior for my needs and I highly recommend it for anyone who works on RC cars or small hobby items that may frequently need to be disassembled repaired and reassembled. Highly recommend this product. I

Genuine and quality product. Works as it should. Couldn’t find any loctite locally other than made in China ones. I’m glad Amazon stock this!
