About Mounts, Brackets & Hardware
Bolts, brackets and mounts are the small parts that hold a motorcycle together and let you attach accessories. Listings include chrome and knurled bolt kits for Harley-Davidson primary and side covers, bodywork fastener kits for Yamaha YZ and WR, brake rotor hardware, handguard bolt kits, windshield mounting hardware, flag mounts for Ranger and General, boot clamps and security seat screws. Riders buy them to replace stripped, rusted or lost bolts, to dress up covers or to mount accessories.
Match the thread first. Inch bolts such as 5/16-18 give the diameter and threads per inch, while metric bolts such as M5 x 16 give the diameter and length in millimeters, and the two do not interchange. Then match length, head style and finish. A kit made for a model, such as a Sportster primary cover kit or a Softail and Dyna cover kit, has the right number and lengths. Brake rotor and handguard bolts are safety-critical, so use the grade the maker specifies and follow the service manual for tightening and thread locker.
Brands here include Mustang, UFO, Bolt, Atlantis and Cobra. For the panels fasteners hold on, see Fairings, Plastics & Body Kits, and for windshields see Windshields. The wider group is Body & Frame.
FAQs on motorcycle bolts, brackets and hardware
How do I read a bolt size such as 5/16-18 or M5 x 16?
In 5/16-18, 5/16 inch is the diameter and 18 is the number of threads per inch. In M5 x 16, M5 is a 5 millimeter diameter and 16 is the length in millimeters. Inch and metric threads do not interchange, so compare against your original or check the manual.
Can I replace original bolts with chrome dress-up bolts?
For covers and trim, yes, if the thread, length and head fit and the listing is made for your model. Do not swap safety-critical fasteners, such as brake or handguard bolts, for cosmetic ones unless the maker says they are suitable, and follow the service manual's tightening guidance.
Should I use thread locker on motorcycle bolts?
Only where the service manual says so. Some fasteners, such as those on brakes and certain covers, call for a specific locking compound or a locking washer, while others should be left dry. Using the wrong product can make removal hard or leave a fastener loose.
How do I choose the right bolt length?
Use the original as a guide: measure from under the head to the tip, and match the thread. A bolt that is too short may not grip enough threads, and one that is too long can bottom out or hit parts behind it. Kits listed for your model include the right lengths.
