This is the first puzzle bolt that Two Brass Monkeys has to offer. It was designed by Ali (part of Two Brass Monkeys) in 2015 and has a unique solution.
Ali's Bolt is a fairly heavy bolt and larger than many puzzle bolts already out there. The aim is to remove the nut. It is engineered to a very high standard and will certainly compliment any other puzzle bolt designs you may have. It is 320 grams and 100 mm in length.
