With the round-head bumps, the detachability is excellent and it is convenient for mounting and replacement. | 2018-01-11 |
20180010627 | Fastener With Preset Securing Member - A bushing includes an upper collar with a lower sheath and an annular shoulder intermediate the collar and sheath. The collar has a plurality of spaced apart notches and the sheath has a plurality of spaced apart slits that may be circumferentially aligned with the notches. The sheath has a plurality of spaced apart ribs projecting outward circumferentially offset from the slit for assisting in maintaining the sheath within a hole in a fastener with the annular shoulder against the fastener. A securing member with an elongate shank extending from a head with a distal portion is maintained in the longitudinal opening in an upright position aligned with the hole. As the fastener is driven longitudinally through the opening and hole, force from the fastener causes the bushing to break away and yields direct contact between the securing member head against the top surface of the fastener. | 2018-01-11 |
20180010628 | CAPTIVE BOLT AND RETAINER - A fastener system includes a bolt and a retainer. The bolt has a first end and an opposing second end, wherein a recess having a predetermined shape is defined in the first end of the bolt. The retainer includes a first end having a predetermined shape configured to be inserted within the recess in the first end of the bolt and a second end configured to couple about the second end of the bolt. A method of fastening parts together with the fastener system includes inserting the first end of the retainer into the recess of the bolt, deflecting and/or rotating the retainer in a direction to bring the second end of the retainer into proximity with the second end of the bolt, and securing a nut to the bolt. | 2018-01-11 |
