The material used for the majority of aircraft solid shank rivets is aluminum alloy. The temper designation and strength are indicated by special markings on the head of the rivet. The designation of the solid shank rivet head type, such as universal head, roundhead, flathead, countersunk head, and brazier head, depends on the cross sectional shape of the head. They are identified by the kind of material of which they are made, their head type, size of shank, and their temper condition. Solid shank rivets are generally used in repair work. Two of the major types of rivets used in the aircraft are the common solid shank type, which must be driven using a bucking bar, and the special (blind) rivets, which may be installed where it is impossible to use a bucking bar. In addition to their use for joining aircraft skin sections, rivets arc also used for joining spar sections, for holding rib sections in place, for securing fittings to various parts of the aircraft, and for fastening innumerable bracing members and other parts together. The shop head functions in the same manner as a nut on a bolt. The second head, formed either by hand or by pneumatic equipment, is called a "shop head." The shank of the rivet is placed through matched holes in two pieces of material, and the tip is then upset to form a second head to clamp the two pieces securely together. A head is formed on one end when the rivet is manufactured. It is the most common method used to fasten or join aluminum alloys in aircraft construction and repair.Ī rivet is a metal pin used to hold two or more metal sheets, plates, or pieces of material together. Riveting is satisfactory from the standpoint of strength and neatness, and is much easier to do than welding. To make a good union and a strong joint, aluminum parts can be welded, bolted, or riveted together. The process used must produce a union that will be as strong as the parts that are joined.Īluminum and its alloys are difficult to solder. Several methods are used to hold metal parts together they include riveting, bolting, brazing, and welding. Also available with quick change shaft.An aircraft, even though made of the best materials and strongest parts, would be of doubtful value unless those parts were firmly held together. 0005 increments: high speed Ball Bearings hardened and ground shaft with wrench flats: ball thrust bearing and left handed lock ring. To complete the part number, add the single letter which expresses the foot-piece, or "skirt style"ĭeveloped for the Boeing Company, this microstop features stop adjustments in. the ball thrust bearing ensures accuracy and repairability of the depth setting. Each series has full 5/16" travel, and a graduated depth adjustment in. The AT441HBS-Series enhances that performance with the use old ball bearings. The spindle of our AT441HS-Series Microstop rides on needle bearings, ensuring continuous smooth, cool operation at speeds to 5000 rpm. the cups are machined in accordance with MIL-STD GGG-R-435b, and a blended radius between cup and chamfer eliminates coining. Part # AT108A-33PC includes five additional 3/8" diameter flush sets.ĪTI squeezer sets are manufactured from high-grade shock resistant tool steel and are polished both before and after heat treat to purge tool marls and ridges. The hole pattern of the Kit plate is engraved for identification and tool control. The AT108A-28PC contains 28 of the most commonly used rivet squeezer sets:23 universal cupped sizes, and five 1/2" diameter flush. Ideal for structural and sheet-metal technicians, home builders, and students. FourOf the most common bucking bars:eight cupped sets for3/32", 1/8", 5/32, and 3/16" AN470 universal head rivets three flush sets for AN426 rivets: two retainer springs an air regulator for adjusting hammer Blows:Tool oil an attractive molded rubber case for organization and storage and a 33X or 4X rivet gun. This kit provides all the essentials for straight and offset riveting. Their tools are used by every major manufacturer of commercial and military aircraft as well as airlines, MRO organizations and governmental repair stations. ATI-brand tools have been the favorite of airframe and sheet metal mechanics for more than a half-century.
