Publication number: 20140321946Abstract: A fastener includes a nut having an anterior portion, a posterior portion and a threaded bore with a center axis extending from the anterior portion to the posterior portion, the outer surface of the posterior portion having an annular camming surface concentric with the center axis, the camming surface having a radius that decreases along the direction of the center axis away from the anterior portion toward the posterior portion; and a sleeve having a first end having an internal annular camming surface that engages the nut camming surface concentrically with the center axis and a second end having a thrusting surface. Tightening the fastener on an externally threaded member applies a force to the thrusting surface parallel to the center axis resulting in the nut camming surface and the sleeve camming surface cooperating to compress a portion of the threaded bore toward the threaded member.Type: ApplicationFiled: April 30, 2013Publication date: October 30, 2014Applicant: R B & W Manufacturing LLCInventor: DAVID E.

Publication number: 20120219377Abstract: A clinch nut for attachment to a plastically deformable metal substrate is provided. The clinch nut comprises a body portion with a central axis and a punch portion extending from the body portion and coaxial with the central axis. The body portion includes an annular-shaped surface encircling the central punch portion. The annular-shaped surface includes a plurality of spaced apart lugs encircling the central punch portion. The plurality of lugs each includes a contact surface with a recessed portion where the contact surface engages the metal substrate. A first portion of the contact surface is biased outwards from the central axis upon insertion in the metal substrate to form at least one lug flare during attachment of the nut to the metal substrate. A portion of the metal substrate is entrapped between the at least one lug flare and the body portion.Type: ApplicationFiled: December 22, 2009Publication date: August 30, 2012Applicant: R B & W MANUFACTURING LLCInventors: W. Richard Pamer, Douglas P. Dennis

Patent number: 8062141Abstract: A metal clinch fastener has portions thereof selectively hardened to enable use of the fastener with metal members of differing hardness values. The selective hardening of the fastener enables mounting with application of required forces for piercing and/or plastic deformation of the metal member without undesirable deformation or distortion of the fastener. The screw thread region or zone of the fastener has a relatively lesser hardness suitable and may be pre-threaded or later threaded by engagement with a thread forming screw.Type: GrantFiled: May 19, 2010Date of Patent: November 22, 2011Assignee: R B & W Manufacturing LLCInventor: W. Richard Pamer
