AEROTIGHT NUT A torque prevailing nut of all metal construction. The. nut is slotted in two places which, after the nut has been. When the. nut is screwed onto the bolt thread the two slotted parts. Their stiffness. causes the nut threads to bind onto the bolt threads and. Aerotight is a registered. The Premier Screw and Repitition Co. Ltd of. Woodgate, Leicester, United Kingdom, LE3 5. GJ. ANTI FRICTION COATING AF coatings are dry lubricants consisting of suspensions. PTFE or molydbenum. Such coatings. can be applied to fastener threads to replace metallic coatings. By careful selection of the lubricants, AF. The coatings are permanently bonded to the metal surface. ANTI SEIZE COMPOUND An anti seize compound is used on the threads of fasteners. The purpose of the compound depends. Acronis True Image Home 2009 Crack Keygen Online there. It can prevent galling of mating surfaces. In some. applications it is used to improve corrosion resistance. Thirdly. it can provide a barrier to water penetration since the. AUTOLOK NUT A torque prevailing nut of an all metal construction. Covered by UK patent 1. GKN. Screws and Fasteners Limited. ALLOWANCE An intentional clearance between internal or external. Not all classes. of fit have an allowance. For metric threads the allowance. ANAEROBIC ADHESIVE An adhesive which hardens in the absence of air, such. A tightening procedure in which a fastener is first tightened. The Log File For Request Is Empty 0 Bytes. Frequently bolts are tightened beyond their. Bolts of short length can be elongated. Because. of the bolt being tightened beyond yield, its re use is. BASIC THREAD PROFILE This is the theoretical profile of external and internal. BEARING STRESS The surface pressure acting on a joint face directly as. BIHEXAGON HEAD A bolt or screw whose cross section of its head is in. BLACK BOLTS AND NUTS The word black refers to the comparatively wider tolerances. BOLT A bolt is the term used for a threaded fastener, with. BREAKAWAY TORQUE The torque necessary to put into reverse rotation a bolt. BREAKLOOSE TORQUE The torque required to effect reverse rotation when a. BRITISH STANDARD BRASS A specialist thread form based upon the Whitworth thread. BSF British Standard Fine. A thread form based upon the British. Standard Whitworth form but with a finer thread more threads. This thread form was first. BS 8. 4. 1. 95. 6. BSW British Standard Whitworth. A thread form developed by. Sir Joseph Whitworth in 1. The thread form has rounded. BS 8. 4. 1. 95. 6. This thread form was superceded by the Unified thread. BUMP THREAD A modified thread profile patented and trade mark of the. Bosco Tool Inc. The thread form has a small projection at. By doing this it is claimed. CADMIUM ELECTROPLATING Coating of threaded fasteners with cadmium can provide. The appearance. of the coating is bright silver or yellow if subsequently. The friction values associated with this coating. A chromate conversion coating. Cadmium is not now frequently used because of. C or when contact with food is possible. CLAMPING FORCE The compressive force which a fastener exerts on the joint. CLASS OF FIT The Class of Fit is a measure of the degree of fit between. Three main Classes. Fit are defined for metric screw threads FINE This has a tolerance class of 5. H for internal threads. MEDIUM This has a tolerance class of 6. H for internal. threads and 6g for external threads. COARSE This has a tolerance class of 7. H for internal. threads and 8g for external threads. For Unified threads, a similar designation as for metric. The thread classes used are 1. A, 2. A and. 3. A for external threads and 1. B, 2. B and 3. B for internal threads. CLEVELOC NUT A torque prevailing nut of all metal construction. The. collar of the nut is elliptical in cross section and it. The. nut is pre lubricated to reduce the torque needed when tightening. COEFFICIENT OF FRICTION A dimensionless number representing the ratio of the friction. Typically for threaded connections. In relation to threaded fasteners, the coefficent of friction can be further sub divided into the coefficient of friction between the threads and the coefficient of friction under the nut face. There is in general a difference in values between the two coefficients due to typically the contact surfaces being different. For example, a zinc plated nut on a zinc plated bolt, the thread coefficent of friction would be due to zinc plating contacting zinc plating. The nut face coefficient of friction would be due to zinc plating contacting the joint surface finish. COMMINGLING A term used to describe the undesirable practice of mixing. CONELOC NUT The Coneloc is an all metal prevailing torque type self locking nut. The. locking action is achieved by localised precision deformation of the thread. When the nut is tightened onto the. Coneloc is a trade mark of NUTS BOLTS Limited. CONE PROOF LOAD This is an axial applied force applied to a nut when it. Failure in this test is usually due. The intention of the test is to introduce. This type. of test is sometimes applied to nuts which are intended. CREEPCreep is deformation with time when a part is subjected. Metals creep can occur at elevated temperature. Creep resistance is an important property. Gasket materials are designed to flow. The amount of creep sustained tends to increase with temperature. However once the tightening is completed it is important. If this stress is reduced to. DECOMPRESSION POINT The point at which there is zero pressure at the joint. If. the applied force is increased beyond the decompression. Analytically, a. criteria of joint failure is often taken as when the applied. This. is because forces acting on the bolts can dramatically. Loading beyond this point can also. This process can continue until bolt failure does. The failure can be by fatigue or other mechanism. It is for this reason that it is. DACROMET A high performance surface coating that can be applied. The coating consists of passivated zinc flakes.
