It has a long, thin body and a flange at one end, resembling a T in profile. The flanges of T Nuts often have hooks or serrations on the prongs that sink into a wooden work piece, providing better retention. In 1969, the first 4 prong t nut with the 8 sided base was patented. Unlike the standard round base t nuts, the 8 sided T nuts can be fed efficiently and reliably via machine.

A jam nut is a low profile type of nuthardwarenut , typically half as tall as a standard nut. It is commonly used as a type of locknut , where it is jammed up against a standard nut to lock the two in place. It is also used in situations where a standard nut would not fit. A jam nut can also refer to any nut that is used in the same function. Use A jam nut is often used when a nut needs to be locked in place without clamping against another object. The jam nut essentially acts as the other object , as the two nuts are tightened against each other. They can also be used to secure an item on a fastener without applying force to that object. This is achieved by first tightening one of the nuts onto the item. Then the other nut is screwed down on top of it. The inner nut is then slackened back and tightened against the outer nut. Note that jam nuts can be unreliable under significant loads. If the inner nut is torque d more than the outer nut, the outer nut may yield engineering yield . If the outer nut is torqued more than the inner nut, the inner nut may loosen up. ref Citation last Barrett first Rich title Fastener Design Manual url http www.designnotes.com companion barrett.html accessdate Mar 20 2009 . ref References reflist Category Fasteners ... more details

Unreferenced date August 2008 A square nut is a four sided Nuthardwarenut . Compared to standard hex nuts, square nuts have a greater surface in contact with the part being Fastener fastened , and therefore provide greater resistance to loosening though also greater resistance to tightening .

For a barrel nut with a flange Sex bolt A barrel nut is a specialized nuthardwarenut that is commonly used in aerospace applications. It is used to bolt thin sheet metal parts to larger, often billet or forging forged , parts. The barrel nut is a round slug, or formed sheet metal part with screw thread threads perpendicular to the length of the nut. The nut sits in a hole inside the forging and a standard machine screw is threaded into the barrel nut from outside the sheet metal. They are preferred over a standard nut and bolt, because they don t require a flange to be machined or forged onto the receiving part, thus reducing weight. ref Smith, pp. 107 108. ref References Notes reflist Bibliography Citation last Smith first Carroll author link Carroll Smith title Carroll Smith s Nuts, Bolts, Fasteners, and Plumbing Handbook publisher MotorBooks MBI Publishing Company year 1990 url http books.google.com ?id A81HmmRCN7YC isbn 0879384069 .

The frangible nut , commonly confused with an explosive bolt , is a component used in many industries, but most commonly by NASA to sever mechanical connections. It is, by definition, an explosively splittable Nuthardwarenut . The Screw bolt remains intact while the nut itself is split into two or more parts. ref cite web url http www.collectspace.com collection artifacts sts sts31fnut.html title The Editor s Collection STS 31 SRB Hold Down Post Frangible Nut publisher collectSPACE date accessdate 2009 07 22 ref Shuttle usage Frangible nuts secure the solid rocket boosters SRB of the space shuttle , which are bolted to the mobile launcher platform MLP until liftoff. On the shuttle, they are separated using a NASA standard detonator or NSD. The space shuttle uses two NSDs for the frangible nut atop each of the four 28 long, 3.5 diameter bolts holding each SRB to the MLP. Once detonation occurs, the shuttle lifts free of the MLP. The broken nut and any shrapnel from detonation is captured by energy absorption material, such as metal foam , to prevent damage to the shuttle. In case of NSD failure, or incomplete clearance of the nut from the bolt, the SRB has ample thrust to break the bolt itself and launch unhindered. Frangible nuts are also used for separation of the two aft structural attachments of the external tank prior to orbital insertion. The attach bolts are driven by the explosive force of the NSDs and a spring into a cavity in the tank strut. The nuts and all residual pieces of the NSDs are caught in a cover assembly within the shuttle. References references Spacecraft stub Category Fasteners ... more details
Orphan date November 2010 A well nut is a type of fastener used to blindly fasten a piece much like an molly fastener molly bolt and to seal the bolt hole. It consists of a flanged neoprene Bushing isolator bushing with a Nuthardwarenut embedded in the non flanged end. The bolt is passed through one of the pieces to be fastened and threaded onto the nut from the flanged end. The non flanged end is then inserted through the other piece to be fastened. As the bolt is tightened, friction from the neoprene flange against the piece being fastened prevents the nut from turning. The bushing is compressed by the nut, forming a lip behind the piece being fastened, which compresses the fastened piece and seals the bolt hole. It can also be used in a solid workpiece. As the screw draws the embedded nut towards it, the walls of the well exert a force on the hole walls, anchoring it. ref name smith Smith, pp. 112 114. ref Well nuts are not particularly strong, but are useful for sealing holes and or isolating vibrations. ref Smith, p. 114. ref It was originally developed by the United Shoe Machinery Corporation . ref name smith References reflist Bibliography Citation last Smith first Carroll author link Carroll Smith title Carroll Smith s Nuts, Bolts, Fasteners, and Plumbing Handbook publisher MotorBooks MBI Publishing Company year 1990 url http books.google.com ?id A81HmmRCN7YC isbn 0879384069 .

Image Xcelite nut driver.jpg thumb A Xcelite nut driver. A nut driver is a tool for tightening nuthardware nuts and screw bolts . It essentially consists of a socket wrench socket attached to a shaft and cylindrical handle and is similar in appearance and use to a screwdriver . They generally have a hollow shaft to accommodate a shank onto which a nut is threaded. They are typically used for lower torque applications than wrenches or socket wrench ratchets and are especially popular in the electronics industry. Variations include T shaped handles for providing the operator with a better grip, ratchet device ratcheting handles, sockets with recessed magnets for holding fasteners , and flex shafts for bending around obstructions. A spinner handle is a shaft and handle with a drive fitting most commonly at the end for attaching interchangeable sockets. This allows one to use a single handle with a number of sizes instead of having a separate nut driver for each size. However, a spinner lacks the benefit of a hollow shaft thus, a common alternative system is a single handle with interchangeable shafts in each size.
