Precision Machined .250" Flat Head Pivot
| Shaft Diameter: | .2450" |
| Shaft Tolerance: | +-.0002" |
| Shaft Length: | .550" |
| Screw Size: | 8-64 |
| Heat Treated: | Yes |
| Head Type: | Flat |
| Head Diameter: | .475" |
| Head Thickness: | .125" |
| Material: | 17-4 Stainless |
Our pivots have the tightest tolerances and are more consistent than any pivot available. We first sold precision machined pivots in 2007. The shaft tolerances on all our pivots is +-.0002" and we maintain those tolerances today.
The most important attribute of all our pivots is consistency. If any of our pivots are damaged, a replacement pivot can be installed in a few minutes and they always fit. We've been told this multiple times.
On the shaft below the head is a .0005" raised area or ring. The purpose of the ring is to a create friction fit between the liner/frame and pivot. The fit is tight enough to prevent the pivot from turning, but allows easy removal. We recommend reaming, not drilling, the blade and liners, to .2500" diameter. The pivot will pop into the liner/frame and not move if the hole is properly reamed to the correct diameter.
The shaft is threaded 8-64. The fine pitch of the threads make it easy to adjust the blade tension. We were the first supplier to make pivots and screws with 64 thread per inch. Other suppliers have followed our lead.

The barrel pivots are threaded from one end all the through. They are not threaded from each end like some barrel pivots on the market. The difference is pivots threaded from each end will almost never match where they meet inside the pivot. The result is a cross threaded screw. You will never have this problem with our barrel pivots.
The shaft is threaded 8-64. The fine pitch of the threads make it easy to adjust the blade tension. We were the first supplier to make pivots and screws with 64 thread per inch. Other suppliers have followed our lead.

Swiss Lathe
Screws machined on a Swiss lathe are the best you can buy. Our screws are threaded the full length of the shaft. The thread relief under the head does not compromise screw strength.
White Timascus
It is difficult to make screws from Timascus. The pattern on every screw is different and goes all the way through the screw. If you reshape or modify the screw, the pattern will change.

Swiss Lathe
Screws machined on a Swiss lathe are the best you can buy. Our screws are threaded the full length of the shaft. The thread relief under the head does not compromise screw strength.
18-8 Stainless
18-8 is a group of stainless steel alloys with 18% chromium and 8% nickel. Some of the alloys are 301, 302, 303 and 304. These alloys are austenitic and cannot be heat treated and hardened like martensitic alloys. Most 18-8 screws have a hardness around the low to mid 30s HRC. The advantage of 18-8 is corrosion resistance.
Passivation
The purpose of passivation is to remove iron from the surface. Iron on the surface of a part can be the place where corrosion starts. Passivation eliminates the potential problem. All stainless steel alloys have an oxide layer on the surface that resists corrosion.
Nitriding
Nitriding is a process that diffuses nitrogen into the surface of a metal to create a thin hardened surface. Our nitrided 18-8 screws have a surface hardness above 70 HRC. The steel below the surface is soft and unaffected by the nitriding.
Other benefits of nitriding are extra corrosion resistance and a color change. The color of our nitrided screw range from gold to blue. The majority are a brown / bronze color with some iridescence. The color is in the surface of the steel but can be ground off. Nitriding is not a coating or electroplating. It will not chip and peel like chrome or nickel plating.

The advantage of 17-4 stainless is strength and hardness. This alloy is precipitation hardening. Our 17-4 stainless screws are heat treated to the mid 40s HRC.

This thrust bearing works with all our .250" pivots.
This bearing was designed in house and made here in the United States. We try to buy all domestic materials. The cage is thick enough so only a small portion of the bearing balls protrude from the cage. The thicker cage keeps larger pieces of debris from getting to the balls.

| ID & OD Tolerance: | +-.005" |
| Thickness: | .020" |
| Heat Treated: | HRC 59-60 |
| Material: | Stainless |
We designed these thrust washers to be used with caged bearings. The balls in the caged bearing roll on a smooth flat surface. The washers can be used in a pocket of titanium, carbon fiber or G10. The washers are thick enough to resist cupping.
Some knifemakers use the washers without bearings. The washers are finished to a very high grit and then polished. This makes the knives have a smooth action.
