Abstract: A nut (30) includes a main portion (30A) formed with a bolt insertion hole (31), into which a bolt is insertable, and a wedge portion (30B) projecting from the main portion (30A) in a radially outward direction of the bolt insertion hole (31) and having a width smaller than that of the main portion (30A). Thus, parts (27B) extending lateral to the wedge portion (30B) in parallel with a projecting direction of the wedge portion (30B) can be made thicker than parts (27A) extending lateral to the main portion (30A). Therefore, the parts (27B) that resist an accompanying rotation of the nut (30) can be thickened without enlarging a housing (20), with the result that strength against the accompanying rotation of the nut (30) can be ensured.

Abstract: A multifunction wheel nut cap is used on motor vehicle to indicate loosening and rotation of a lug nut. On large trucks on which the lug nuts have to be frequently torqued to prevent the lug nut from loosening and turning until it drops from the wheel bolt, the indication of rotation and limiting of the rotation prevents the lug nut loss and requires tightening only when there is an indication that the lug has become loose. The Wheel cap nut device gives a visual warning when a nut has become loose. It also prevents water and contaminants from penetrating the lug nut and bolt threads.

Abstract: A threaded insert for use in a composite and/or honey-comb matrix has a nut member disposed within a plastic housing. The threads of the nut member have a free running thread section and a thread lock section. When a fastener is made up into the nut member, a surface on the nut member engages an opposite-facing surface on the plastic housing, thereby reversing the nut loading from tensile loading to compression loading. A thermoplastic embodiment of the nut member may be fabricated to meet the specifications of aircraft manufacturers required for the SL2334 insert, including thread reusability, tensile loading (pullout load), shear, and interchangeability with the metal component currently in use.

Abstract: A bolt has a pointed end with cutting edges. The cutting edges may have knurls (grooves) or ridges, and may have a spiral arrangement. The bolt may have a convex end, such as a cone end or a curved end. A plurality of bolts may be used as part of a reinforcing bar splice that also includes a sleeve. The bolts engage threaded holes of the sleeves. As the bolts are tightened, they bore into the receiving bar ends, securing the bar ends within the sleeve. Cutting edges on the bolts aid in boring the ends of the bolts into the reinforcing bar ends. Using cutting edges on the bolt ends allows deeper penetration of the bolts into the reinforcing bar ends, without increasing the amount of torque used.
