Velocity Washer is a patented technology designed to eliminate galling and give you 30x faster disassembly. With over 100 million hours in use, Velocity Washer increases production and reduces labor costs by eliminating galled and seized nuts that cause production delays during disassembly.

Velocity Washer is installed just like a normal washer. To install, simply place the Velocity Washer on the stud. Due to its symmetric design, it can’t be installed in the wrong orientation, delivering the simplest installation. You then torque the nut on using standard breakout procedures: there are no special tools required. Just put them on and go.

For breakout, all you need to do is turn the nut 12 degrees to the left. The Velocity Washer will pop and all load will be removed, allowing the nut to easily run off – and giving you a breakout that’s 30x faster than ever before.

Velocity Washer enhances worker safety by eliminating hot bolting (AKA single stud changeout), torches, and unnecessary time on tools.

Patented – US Patent #8,579,572 and several other worldwide patents.

Testimonials

“We have the Velocity Washers on two of our blowdown exchangers. We typically have to torch cut these large studs; with the Velocity Washers they spun off just like shown on the promotional videos. We re-used the studs and nuts.”

Lead Reliability Engineer

“The same reactor head after installation of Velocity Washers, took only 1-2 hours in total to disassemble, with no damage to capital equipment, no hot work needed and no studs needed replacing.” 

Turnaround Planner
“Our results with the Velocity Washers were very good. Normally we would budget four 10 hour shifts of gouging. This involved a substantial hoarding and of course time. With the Velocity Washers it took us a bit over half a shift.”
Maintenance Coordinator

Frequently Asked Questions

Velocity Washer sizes range from 3/4” – 5” bolt diameter. Contact us for sizes outside this range. 

No, the Velocity Washers are designed to replace a standard hardened washer, so no additional tooling is needed.  

No, you only use one Velocity Washer per stud on the same side of the flange the torque wrench will be applied.  

Velocity Washers will fit wherever a standard washer will fit.  

Velocity Washers are typically double the height of a standard washer. We have a full spec sheet available on request.  

Velocity Washers are made from HT4340, which is a stronger material than standard bolts. You will yield the stud before you damage the Velocity Washers.  

Velocity Washers are typically designed to relieve 0.12” of bolt stretch. That is equivalent to 100% bolt yield on a 34” grip length.  

The load-bearing area of the Velocity Washer is greater than that of the bolt, and it is made from a stronger material. So, anything the bolt can take, the Velocity Washer can take.  

The max temp is around 850F. If we have an application that goes above 850F, we have other alloys that can take that max temperature up to 1100F safely.  

The Velocity Washers need less torque to turn than a standard bolt, so no additional torque is needed.  

No vibration issues. The Velocity Washers have been tested over 30,000 cycles, applying 30 G acceleration and 15,400lbs of shaker force. The Velocity Washers passed the test. See video:

Standard Velocity Washers are made from HT4340 which has been heat-treated and stress relieved. In special circumstances, we can cut Velocity Washers in different materials based on your specific needs.
