For some derailleurs or other instances where the Allen key depth is extra deep this product may fit as well.
Insert a hex tool into each bolt you'd like to secure, to determine which size Hexlox you need. You also need to measure the depth of the hex bolt socket to select the correct Hexlox Lefty length.
Lefty 50 = 7mm total length including Hexlox
Lefty 60 = 11mm total length including Hexlox
You also need todetermine if your bolts are magnetic - or not. Use a fridge magnet to do that. Hexlox works with steel bolts.If your hex bolts are non-magnetic - Aluminium, Stainless Steel, or Titanium - you need to add a Hexlox For Non-Magnetic Bolts to your order
