Patent number: 11986893Abstract: A hardware fastener with a movable threaded element suspended within a cavity formed in a body. The movable threaded element has an internal surface with threads for cooperating with a threaded fastener. The movable threaded element is suspended in the cavity by the one or more spring-like members such that an area, A, of reduced stiffness is created in the cavity proximate the movable threaded element, thereby allowing the movable threaded element to move a predetermined distance within the cavity when torque is applied to the threaded fastener. The one or more spring-like members store elastic potential energy to prevent the loss of pretension of the threaded fastener that can be caused by heat or vibration. The invention also eliminates the need for a torque wrench when tightening the threaded fastener to a specified torque value.Type: GrantFiled: June 28, 2021Date of Patent: May 21, 2024Assignee: KENNAMETAL INC.Inventors: Alan J.

Publication number: 20100041486Abstract: A fastener includes a t-nut having a barrel and a flange. The flange includes an opening which leads to a threaded barrel. The threaded barrel extends from the opening in the flange to a distal end portion thereof. An end cap has an annular recess on a first side thereof and has a raised annular ridge on a second side thereof. The raised annular ridge of the end cap is affixed to the flange of the t-nut by welding the end cap to the flange. Dirt, water and moisture cannot enter the barrel because the end cap is sealed to the flange. Additionally, the barrel may be relatively short as it is fully threaded prior to the affixation of the end cap to the flange.Type: ApplicationFiled: December 7, 2008Publication date: February 18, 2010Inventor: STEPHEN SELLE
