摘要:
A fastener head (10), preferably a capped fastener head, including a sloping flange (18) surrounding a central wrenching portion, having wrenching surfaces (20), such as axial hexagonal surfaces. A rib (16) disposed on the sloping flange provides stability to a fastener head (10) having such a rib by increasing the overturning moment required to buckle a column comprised of a fastener and driver. The rib is continuous around the flange and is as high as the bottom of the wrenching surfaces to reduce wobble during driving of the fastener head.

Die vorliegende Erfindung betrifft eine Mutter (10, 110, 210) mit einem Mutternkörper (11, 111, 211) und einer auf dem Mutternkörper (11, 111, 211) gehaltenen Kappe (20, 120, 220, 320), dadurch gekennzeichnet, dass an der Außenfläche des Mutternkörpers (11, 111, 211) eine umlaufende Vertiefung (16, 216) oder abschnittsweise umlaufende Vertiefungen (116) vorgesehen sind, in die eine an der Innenfläche der Kappe (20, 120, 220, 320) vorgesehene umlaufende Erhöhung (23) bzw. abschnittsweise umlaufende Erhöhungen (123, 330) eingreifen.
摘要:
A method of covering the head of a screw (24) which has been inserted into a wood structure (14), such as a cabinet, a bookshelf, etc. There is a planar circular cover member (34, 50) made of a moderately flexible plasctic and having an adhesive surface (58). The diameter of the cover member is moderately greater than the diameter of the screw head and the opening in which the screw head is placed. The cover member (34, 50) is placed by positioning a first side portion of the cover adjacent to the opening, and then deflecting the cover member downwardly in a curved position above the srew head opening, keeping the cover properly positioned. Then the person's thumb which grasps an end of the cover member is moved to release the cover member which then snaps into position to cover the opening and become bonded to the surface (42) of the wood structure.

Die Erfindung betrifft eine Schlitzschraube mit einer mittleren Vertiefung (5) mit einem stumpfkegeligen Vertiefungsgrund (8) und vorzugsweise vier radial hiervon ausgehenden, um 90 Grad gegeneinander versetzten Schlitzen (4), deren äußere Wand Teil eines umgekehrten Kegelstumpfes ist, der koaxial zur Schraubenachse liegt und dessen Grundfläche auf der Schraubenkopf-Oberfläche liegt. Die mittlere Vertiefung (5) weist oberhalb des Ver- tiefungsgrundes (8) einen spanlos geformten zylindrischen Führungsabschnitt (7) auf, dessen kreisförmige Querschnittsfläche mit der Kopffläche des den Schlitzen (4) zugeordneten Kegelstumpfes zusammenfällt. Zwischen den Schlitzen (4) sind etwa V-förmige Täler (12) eingeprägt, deren Talgrund (13) auf einer zur Schraubenachse koaxial verlaufenden Mantelfläche eines umgekehrten Kegelstumpfes liegen.
