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 the first nut. 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 ref Citation title The Use of Two Nuts to Prevent Self Loosening url http www.boltscience.com pages twonuts.html accessdate Dec 31 2011 . ref References reflist Category Nuts hardware ... more details

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 do not 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 Cite book 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 .

A flange nut is a nuthardwarenut has a wide flange at one end that acts as an integrated, non spinning Washer hardware washer . This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface. These nuts are mostly hexagonal in shape and are made up of hardened steel and coated with zinc. The flange may be serrated to provide a locknut locking action . The serrations are angled such that they keep the nut from rotating in the direction that would loosen the nut. Because of the serrations they cannot be used with a washer or on surfaces that cannot be scratched. The serrations help in avoiding vibration of nut and increase the holding power of nut. The flange nuts are sometimes provided with a swivel flange which helps in creating a more stable structure without affecting finished product like a serrated flange nut. Swivel flange nuts are mostly used in joining wood and plastic. ref Citation last Barrett first Rich title Fastener Design Manual url http gltrs.grc.nasa.gov reports 1990 RP 1228.pdf accessdate 2008 12 02 . ref Sometimes both faces of the nut are serrated, permitting either side to lock.

Orphan date November 2010 A well nut is a type of fastener used to blindly fasten a piece much like a 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 The well nut was originally developed by the United Shoe Machinery Corporation . ref name smith See also Nuthardware 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 .

Orphan date October 2010 An insert nut provides a threaded socket for a wooden workpiece, similar to a wall anchor . Insert nuts are inserted into a pre drilled hole by one of two means screw in and hammer in. In both cases, the external protrusions bite into the wood, preventing the nut from either turning or pulling out. Insert nuts are advantageous over barrel nut s and T nut s, because they can be installed from one side of the workpiece. Screw in type Screw in insert nuts have an external thread and hex head and are screwed in with an Allen wrench . The screw in insert nuts come in various sizes and take different screw sizes. For example, a 1 4 20 insert nut will take a 1 4 20 inch bolt.

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 . They are also much less likely to become rounded off after repeated loosening tightening cycles. Square nuts are typically mated with square headed Screw bolts . Square nuts are used along with flat washer s in order to avoid damage from its sharp edges and helps to increase the strength of the fastener. History Early nuts were made of wood and were used with wooden pegs. The square shape made it possible to form a tool in order to tighten nut in place. Later wooden fasteners were replaced by steel ones and modern nuts are forged from steel stock bars and used along with steel bolts. Application Commonly used in furniture as a blind nut , they are also used in rail channels in order to prevent turning of rail when pressure is applied. They are also used to make perfect foundation in metal channels for hidden fasteners. Category Nuts hardware ... more details
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 Nuts hardware ... more details
