Tools and Supplies
This article will discuss installing and removing the "star fangled nut" into threadless fork steering columns. For related information see
Threadless headsets are adjusted by pressure on the top bearing race. Pressure is applied when the bolt in the top cap is tightened. The stem bolt must be loosened, making the stem effectively a spacer during the adjustment. The bolt is threaded into the star fangled nut. This is a fitting that is installed into the fork column. The nut is designed not to pull upward. In other words, it is designed not to be removed.
The star fangled nut outer diameter is slightly bigger than the inside diameter of the fork column. This allows the flanges to bite into the fork walls and hold it tight. |
|
Star Fangled Nut Installation Mount the nut with concave side toward tool thread. Hold TNS over steering column and tap on top on TNS with ball peen hammer. Hold tool aligned while striking TNS.
The TNS places the nut about 15mm (9/16") below the top of the steering column. This allows the adjusting bolt to thread fully into the nut for adjustment pre-load.
It can also help maintain alignment to use the stem as an alignment guide. This technique works ONLY if you use the newer longer TNS models. Install stem onto column. Engage so most of the stem sticks up above the column. Do not tighten any upper pinch bolt. Place TNS with nut inside stem and column and tap downward.

Removing Star Fangled Nuts The star fangled nut is basically designed not to be removable. If it is necessary to install another nut, simply use a punch and drive the first nut down until deeper than the new nut will sit. It is not necessary to completely remove the old nut. It is also possible to drive the old nut completely through the column and out the bottom. This will make the nut unusable. It can also work to drill out the center of the nut, and then tap out the remaining pieces. Screw ReplacementThe TNS-1 has a replaceable screw, part #822. Use a small amount of removable thread locking compound on the threads of the new screw. Use 3mm hex wrench in end of screw, and thread into body, leaving about 10 threads exposed.

Branford Bike Online Catalog - Archival Edition brought to you by the former owner of Branford Bike, Tim Brockett via his personal web site, TimsLife.Com |
|
This is an archival edition of the Branford Bike web site from February 2006. Complete with product photos, prices, how to articles and technical specifications it is a treasure trove of accurate, detailed and historical information. In July of 2006 Branford Bike was incinerated by a huge forest fire. No one was hurt but the inventory and buildings were completely destroyed. I witnessed the fire and stayed until the trees were burning in my driveway. At that point I hiked from Branford Bike, through the smoke and embers, down the mountain to my Jeep 3 miles away. I took photos and wrote about the harrowing experience so everyone could see what I saw. My insurance was generous and I later rebuilt my home and started another business selling books. Read the story here. Branford Bike was a huge part of my life for over 30 years; June 1976 to July 2006. I enjoyed those years tremendously and Branford Bike was often a labor of love. I hope you enjoy browsing through the archival catalog. If your visit brings back pleasant memories please share them with me via e-mail at timbrockett@gmail.com . If you find any printed Branford Bike catalogs, advertisments or flyers please scan them as a PDF and email. Or you may mail them via US Post to Tim Brockett, PO Box 1711, Emigrant, MT 59027. Eventually I will post them in a Memorabilia catalog section. Many Thanks and Best Wishes, Tim Brockett |
