Male fastener extractor device
A fastener extractor device for removing fasteners and disengaging the extractor from the so engaged fastener. The extractor includes a threaded main body with a hex drive head end portion and oppositely disposed elongated tool engagement hex body with multiple bracing sidewalls with independent contoured fastener engagement channels for fastener insertion and continued rotational removal. A tubular hex surface extractor nut is threadably disposed on the main body member for reversed thread rotation advancement to physically disengage the tool engagement body from the removed fastener.
Anti-Slip Fastener Driver
An anti-slip fastener driver includes a body, a driving portion and a twisting portion arranged between the body and the driving portion. The driving portion has a plurality of driving recesses and a plurality of sharp corners. A cross sectional area of one end of the twisting portion adjacent to the driving portion is less than that of the other end of the twisting portion adjacent to the body. The twisting portion has a plurality of twisting surfaces formed around an outer periphery thereof in the radial direction of the rotating axis, Each twisting surface has a short side and a long side. A projection line of the short side is not parallel to that of the long side on the reference plane.
Molds and punches for making fasteners and tools
A mold, punch and workpiece are provided. In a preferred embodiment, a tapering outer edge is provided, along with a plurality of rib sets arranged circumferentially about the outer edge, and a ramp. A ramp may be located to facilitate the removal of burrs. Various slot patterns may be provided or formed, including star-shapes/Torx® slots. Using the present invention, a driver bit may be more securely fit to the slot of a screw, for example, allowing the screw to be threaded into a machined part more securely and smoothly, reducing rocking, shaking or tilt.
Range taking shear bolts and drive tools
Range taking shear bolts and bolt installation (drive) tools are described herein, which are configured for use with a variety of range taking connectors and conductors.
Grasping and positioning tool and methods of using it
A grasping and positioning tool is provided that can be used to position a channel insert within channel framing. The tool includes an expandable member that can frictionally engage the channel insert in one position of the tool and release the channel insert in another position of the tool. The tool can be used to permit single handed placement of a channel nut or similar insert into channel framing.
Screwdriver for threaded plug and tightening device
A screwdriver device for a threaded plug includes a structure which extends along an axis and includes a head and a shank connected to a first end of the head, wherein the head has a second end which opens onto a cavity suitable for containing a head of a plug, wherein along the axis the cavity includes at least a first portion having a lateral surface which has a first profile and at least a second portion having a lateral surface which has a second profile which is not coincident with the first profile.
Connecting tool
A connecting tool for connecting a first connecting portion and a second connecting portion of at least one connecting member. The connecting tool may include a shaft. The shaft may include a shaft axis, an operational end, and a body. The shaft may include a recess configured to engage said first connecting portion of said at least one connecting member. The operational end may include an aperture configured to engage said second connecting portion of said at least one connecting member.
FASTENER, DRIVER BIT AND PUNCH TOOL
A fastener includes a screw head and a screw shank. The screw head has a top surface and an inner surrounding surface. The inner surrounding surface has six curved portions and six driven portions disposed in an alternating arrangement. Each of the driven portions has a curved section connected to one of two adjacent curved portions and having a direction of curvature opposite to that of the one of the two adjacent curved portions, a straight section extending along a tangent line of an end of the curved section, and an extension section connected between the straight section and the other one of the two adjacent curved portions.
HEX TOOL
A hex tool including a hex head having a hex portion for engaging socket head cap screws or wrenches. The hex portion also having a body portion extending from the hex portion. The body portion having a cavity disposed therein. The hex tool also includes a handle with an end and a primary handle portion. The end disposed in the cavity to provide the hex tool a significant range of motion during use. Another type of hex tool having a hex head having a hex cavity for engaging a hex head bolt. The hex head also having a body portion extending from the hex cavity. The body portion having a cavity disposed therein. The hex tool also including a handle with an end and a primary handle portion. The ball end disposed in the cavity to provide the hex tool a significant range of motion during use.
Methods and apparatus for a fastener head having a dual zone socket area and a mating driver bit
Methods and apparatus for a fastener head having a dual zone socket area and a mating driver bit according to aspects of the present technology include a fastener configured with driving surfaces adapted to provide enhanced engagement between each other during use. The fastener includes a recessed socket area with a sidewall that has an upper inwardly tapering section and a lower vertical section that extends to the bottom of the recessed socket area. The upper inwardly tapering section of the sidewall may also include an offset relative to the lower vertical section to create asymmetrical driving and removal surfaces. The technology also includes a corresponding mating driver bit configured with mating surfaces to the fastener to provide enhanced engagement between the fastener and mating driver bit. The technology also allows either the fastener or the driving bit to be used with preexisting fasteners and driver bits.
