about-usThe ‘Fredsert’ is a threaded insert patented by the General Dynamics Corporation. This new technology has fostered new attachment concepts, reducing the total overall number of fasteners. The design introduces flexibility in vehicle assembly operations, which reduces assembly costs. Logistical support costs have been reduced, since removal and replacement of the inserts in the field is drastically simplified.

One of the most unique features of a Fredsert is that it doesn’t permanently lock into place. Instead, its patented geometry causes it to break away at approximately 80% of the recommended installation torque value, allowing it to be quickly and easily removed and replaced using the same equipment. By comparison, competitors’ inserts can only be removed by drilling them out and, in some cases, re-tapping to the next largest tap size. This becomes especially difficult if the insert is installed in a large structure or a tight enclosure because access and rigidity are limited.

Another feature that sets Fredserts apart is the fact that Titanium Fredserts are available as a standard product, in addition to those made from Stainless Steel. Titanium Fredserts deliver weight savings of 40% over Stainless Steel inserts of the same size. Titanium inserts from other leading insert manufacturers are either not an option or they are quoted at an extremely high price and long lead time.


A third key benefit that differentiates Fredserts from the competition is the fact that they create a 100% watertight seal without the use of a thread locking agent, such as Loctite. The combination of a tapered thread profile, 100% thread engagement, and a flanged head deliver a perfect seal on the OD thread of the insert. “Blind” Fredserts also deliver a watertight seal on the ID thread, because the ID thread bore doesn’t break through the bottom of the insert.


The Fredsert geometry is effective in that it combines a tapered thread profile, 100% thread engagement, cutting flutes and a flanged head. These unique features deliver a combination of friction fit and material compression that reliably lock a Fredsert in place. The Fredsert was designed to resist vibration, tensile loading and shear loading in the most demanding heavyduty applications.


Fredserts are built in a state-of-theart ISO 9001:2000 accredited manufacturing facility and are certified to Military Specifcation MIL-I-45914A.
