3/8" X 24tpi (please double check and make sure that you need this thread pattern) MADE IN USA from top quality aluminum. FITS Old / Mid school HUBSETS (TNT, Crupi, JP, Some GT & Hutch Hubs) NEW - Never used Aluminum Hub Axle Bearing Locking Collar to fit BMX, Cruiser or any other single speed hub. This is the thread on collar that sits on the inside of your dropouts, and rests against your hub bearing. All hubs have a locking mechanism that holds your hub bearings in place, and stops your wheel from locking up, or coming loose. Some have steel nuts locked against each other, and some have something similar to this. This one fits a 3/8 axle with 24tpi pattern (Threads Per Inch). Please check the thread pattern you need before purchasing. Each bicycle hub uses 2 (one on each side). I am offering these collars per piece depending on how many you need.
