are QR and solid axle threads regulated as standards ?

Wikipedia bicycle wheel -
* Thru axle - a removable axle with a threaded end that is inserted through a hole in one fork leg, through the hub, and then screwed into the other fork leg. Some axles have integrated cam levers that compress axle elements against the fork leg to lock it in place, while others rely on pinch bolts on the fork leg to secure it. Diameters for front thru axles include 20 mm, 15 mm (most common), and 9 mm. Rear axles typically have diameters of 10 or 12 mm. Most thru axles are found on mountain bikes, although some cyclocross and road bikes are using them. Thru axles repeatable locate the wheel in the fork or frame, which is important to prevent misalignment of brake rotors when using disc brakes. Unlike other axle systems (except Lefty), the thru axle is specific to the fork or frame, not the hub. Hubs/wheels do not include axles, and the axle is generally supplied with the fork or frame.
* Female axle - hollow center axle, typically 14, 15, 17, or 20 mm in diameter made of chromoly and aluminum, with two bolts thread into on either side.[1] This design can be much stronger than traditional axles, which are commonly only 8 mm, 9 mm, 9.5 mm, or 10 mm in diameter.[2] (found on higher end BMX hubs and some mountain bike hubs)
Modern[when?] bicycles have adopted standard axle spacing: the hubs of front wheels are generally 100 mm wide fork spacing, road wheels with freehubs generally have a 130 mm wide rear wheel hub. Mountain bikes have adopted a 135 mm rear hub width,[3] which allows clearance to mount a brake disc on the hub or to decrease the wheel dish for a more durable wheel.[3] Freeride and downhill are available with 150 mm spacing.[4]
You needa thread gauge and bolt diameter plastic form from Home Depot..and a vernier maybe at the end of HD's tool rack.
