20090060678 | Fastening element - A fastening element has a core zone ( | 03-05-2009 |
20100014941 | APPARATUS AND METHOD OF MAKING A HEEL-LESS NAIL - A full-round head nail having an offset head is configured with a gusset formed integrally between an undersurface of the offset head and a superior portion of a shank. The head of the nail is relatively thin, and the shank is positioned radially off center of the round head such that no heel is formed at a point tangential to both the head and the shank. The gusset has a lofted surface tapering radially from a roundness at the zero heel to a taper at the toe. The gusset reinforces the junction of the shank with the head, supports the toe of the head, and distributes the force of a load on the head through a longitudinal axis of the shank, preventing the toe from bending or yielding and prevents the shank from yielding to the stresses of the load applied. | 01-21-2010 |
20120321413 | APPARATUS FOR INSTALLING FASTENERS AND EXPLOSIVE LOADS FOR USE THEREWITH - An improved tool for installing an explosively driven fastener as well as an improved explosively driven fastener for use therewith are disclosed. The fastener includes a nail having a head with an explosive load attached thereto in a plastic cap that includes a buffer. The tool has a plurality of concentric cylinders and springs including a muzzle for receiving the fastener head and explosive load. A spring actuated firing pin ignites the load causing it to explode and drive the nail out of the tool. The explosion also automatically resets the tool. The tool and the fastener provide many advantages over existing explosively driven fasteners and the tools used to install them. | 12-20-2012 |

20080232928 | SLEEVE PROTECTED FASTENER - A fastener system for use with a powder actuated tool. The system include a pin, a metallic washer surrounding a portion of the pin at the second end; and a plastic sleeve disposed between the metallic washer and the pin. The plastic sleeve includes a cap portion and an sleeve portion, the cap portion disposed on the top side of the metallic washer coincident with the head of the pin. | 09-25-2008 |
20100034618 | Nail-shaped fastening element - A nail-shaped fastening element having a shank, at whose one end a tip is configured and at whose opposite other end a head is configured, and having a sleeve-shaped washer is disclosed. At a first end facing the tip, the sleeve-shaped washer has a first collar that narrows the opening cross section of the sleeve-shaped washer and, at a second end facing opposite the first end, it has a second circumferentially outwardly disposed collar. | 02-11-2010 |
20110222987 | FASTENER FOR INSULATION - A fastener for use in fastening insulation to a substrate, comprising a fastener body having a head for engagement with an outer face of the insulation, a tubular stem extending inwardly from the head for penetration through the insulation into engagement with the substrate, the stem having a pointed tip portion remote from the head for penetration of the insulation and the stem being hollow to receive a fastening pin having a pointed end fully enclosed within the stem adjacent the tip, the interior of the stem being adapted to receive a fastener guide of a fastening tool operative to drive the pin into the substrate by means of a driving piston propelled along the fastener guide by gas pressure on firing of the tool, the fastener being mounted to the fastener guide prior to penetration of the insulation whereby penetration of the insulation by the stem occurs by manual pressure applied by an operator to the tool prior to firing of the tool to drive the pin into the substrate, the external surface of the stem including an array of fins extending generally axially of the stem to ensure uniform displacement of the insulation material during penetration. | 09-15-2011 |
20120009044 | AUXILIARY MEMBER FOR COIL NAILS - An auxiliary member for coil nails includes a shank and a connection portion which is located at a lateral side of the shank, wherein the shank is pushed by a main pusher of a push mechanism. An extension portion is connected between the shank and the connection portion. The shank and the extension portion are non-parallel to each other, an axis of the shank is not parallel to an axis of the extension portion. The connection portion holds a shank of a last nail of the coil nails. | 01-12-2012 |
