20100018066 | Compact ergonomic thread inspection tool - An ergonomic, self contained hand-held thread inspection tool is power driven, which uses current draw as a surrogate for torque to initiate automatic reversal and gage withdrawal in case of jamming. The distal end carries the thread gage attached to a motor-driven spindle. A thread depth collar sleeve, adjustable by manual turning, concentrically surrounds the thread gage. When threaded into a blind hole or onto a protruding stud and operated, the distal end of the thread depth collar sleeve comes in contact with a part, pushing it against spring force. This movement is internally sensed, causing an indicator to flash, signaling “test OK”, while automatically reversing the spindle to withdraw the thread gage. If during the forward excursion of the thread gage a torque exceeding the pre-set torque limit is encountered, a buzzer is sounded signaling an over-torque problem and the spindle is simultaneously reversed for automatic gage withdrawal. | 01-28-2010 |
20100186242 | Compact ergonomic thread inspection tool - An ergonomic, self contained hand-held thread inspection tool is power driven, which uses a mechanical clutch as a surrogate for torque to initiate automatic reversal and gauge withdrawal in case of jamming. The distal end carries the thread gauge attached to a motor-driven spindle. A thread depth collar sleeve, adjustable by manual turning, concentrically surrounds the thread gauge. When threaded into a blind hole or onto a protruding stud and operated, the distal end of the thread depth collar sleeve comes in contact with a part, pushing it against spring force. This movement is internally sensed, causing an indicator to flash, signaling “test OK”, while automatically reversing the spindle to withdraw the thread gauge.

20100251556 | Thread Gauge Checker - A method is disclosed for measuring the threads of standard and metric female thread bolt and standard and metric male thread nut of must commonly used nuts and bolts and the screw diameters in sizes #0 to #14. A separate set of plug gauges and ring gauges match the thread sizes of both the said standard female and metric female thread bolt gauge sizes. Separate standard and metric thread nut thread sizes are present in separate plug and ring gauges to provide ready gauges to measure threads of bolts and nuts not conveniently measure by plug and ring gauges mounted on a display wall structure for protection of the said gauges for dirt and contaminants. The wall mounted display structure provides an immediately available device for checking thread sizes of nuts and bolts. | 10-07-2010 |
20100281700 | Thread Ring Gauge - A thread ring gauge includes a body having inner and outer peripheries spaced in a radial direction. The body includes a split extending from the outer periphery through the inner periphery, separating the body into two sections respectively having first and second end faces. The first end face includes a groove extending away from the second end face in a width direction perpendicular to the radial direction. The groove extends from the outer periphery towards but spaced from the inner periphery. The groove has a bottom wall facing the second end face. An adjusting member is extended through the first and second sections and movable to adjust a width of the slit between the first and second end faces in the width direction. A gauge block is received in the groove and abuts the bottom wall of the groove and the second end face. | 11-11-2010 |
20110203125 | INSPECTION METHOD OF GAUGE FOR A SELF-LOCKING THREADING OF A TUBULAR CONNECTION USED IN THE OIL INDUSTRY - A method and a gauge for inspecting a self-locking threading provided close to one end of a tubular component used for exploration or operation of hydrocarbon wells, the threading including a lead with a constant width and thread root widths that increase in the direction of a distal surface of the tubular component. The gauge can be displaced in the self-locking threading to a locking position, the locking position then being marked and compared with a reference locking position. | 08-25-2011 |
20120030956 | METHOD AND APPARATUS FOR THREAD TESTING BY DISTANCE MEASUREMENT - Apparatus for thread testing, comprising at least one plug gauge ( | 02-09-2012 |
20130067753 | BOLT SORTER FOR DETERMINING SIZE AND THREAD PITCH OF BOLTS - A bolt sorter quickly and easily determines the size and thread pitch of a bolt. The bolt sorter includes a plurality of semi-circular threaded profiles that are sized and have threads cut to accept bolts into the profile. If the bolt is of the correct diameter and thread pitch, the bolt will fit into the semi-circular threaded profile. Unlike conventional devices that usually require the bolts to be threaded into holes, users can quickly insert bolts into the threaded profiles of the bolt sorter to determine their size and thread pitch. The bolt sorter can be sized for standard and metric sized bolts and can include multiple thread pitch profiles for each bolt diameter. | 03-21-2013 |

20160377404 | CONTROL RING - The invention concerns a control ring to verify a fastener comprising an enlarged head and a cylindrical shaft extending along an axis, the shaft comprising at least one band of coating parallel to axis (A), the band extending over a circumferential width. The ring comprises a cylindrical tubular body extending along an axis of revolution (B) and two opposite extremities, a first extremity comprising two adjacent arc segments, each arc segment having an end wall extending in a plane perpendicular to the axis of revolution (B) of the ring, the planes of the two walls not being one and the same and axially offset from the first extremity. Each arc segment comprises at least one side wall extending over a radial plane going through the axis of revolution (B) of the ring. The width of an arc segment makes it possible to verify a minimum band width, and the width of the two arc segments makes it possible to verify a maximum band width. | 12-29-2016 |
