It might be unusual to think of bolts and nuts as cutting-edge technology, but for at least 1, years these fasteners were nothing less.

Usable in heavy sheet metal and diecastings. Type CA point: A thread forming screw with either coarse or fine pitch machine screw thread. Same as Type C except with a Gimlet point. The locating point works better than Type C where holes between two adjoining pieces of sheet metal may be somewhat misaligned. Tri-Round: A thread forming screw in mostly coarse machine screw threads. Three vertexes perform a roll -forming process to form mating threads.
Much better thread forming than Type C or CA, and drives with less torque. Lo-Driv: A thread forming screw in mostly coarse machine screw threads. The point and body design requires low end -load for starting and low drive torque for seating. The full degree body above the point provides excellent strip-to-drive ratios. Provides a low large diameter head, but with characteristically high outer edge along the outer periphery of the head where drive action is most effective for high tightening torques.
Slightly different head contour where supplied with recessed head. See dotted line. This head was the most universally used design in the past. The small diameter head increases the pressure applied on the smaller area and can be assembled close to flanges and raised surfaces BINDING HEAD Straight Side : Most generally used in electrical and radio work because of its identifying undercut beneath the head, which binds and eliminates fraying of stranded wire.
A medium -low head with ordinarily sufficient bearing surface. Not recommended as a Phillips Recessed head -see Pan Head for better functional design. A low, large diameter head that can be used to cover larger diameter clearance holes in sheet metal when additional play in assembly tolerance is required. Possesses a truss head on a square shank, which resists rotation when located or driven into place.
Over 1 to 2 in. Over 2 in. Max Min 4 0. Some wood screws are only partially threaded depending on the length. Used with drilled, punched or nested holes in sheet metal, resin impregnated plywood, asbestos combinations, among others. Not recommended for new design. Normal limitations of type B apply. Type B point: A thread forming screw for use in heavier metal.
Larger root diameter with finer thread pitch for light and heavy sheet metal non -ferrous castings, plastics, impregnated plywoods, asbestos combinations, and other materials. Produces a fine standard machine screw thread for field replacement. Type 17 point: A thread cutting screw for wood with a coarse tapping screw thread and a special long sharp point fluted to capture chips. Type 23 point: A thread cutting screw in the fine thread series offering maximum thread cutting area and excellent chip clearing, with minimum tightening torques.
Type 25 point: A thread cutting screw similar to type 23 point except with coarse Type B thread. For plastics and other soft materials with large chip clearing and cutting edges. Type F point: A thread cutting screw with machine screw thread with blunt tapered point, having multi -cutting edges and chip cavities. For heavy gauge sheet metal, alu -minum, zinc and lead die castings, cast iron, brass and plastic. Drill Size No. Hole Diameter 00 6 0. Related Papers. By Ashman Noordin.

This short guide is intended to give a very basic introduction to ISO metric nuts and bolts. It is intended for those working in plant and machinery maintenance to give enough information on to ensure that correct replacement parts are identified and used. Few parts are as critical in the assembly of modern machinery as the nuts and bolts which hold it all together and, at first sight, it seems that all metric bolts are basically the same. In fact, of course, nothing could be further from the truth. There are no fewer than 5 different threads for different applications and 10 different standard strength grades defined for each size of bolt. The situation on is almost as complex with metric nuts which come in a wide variety of types full, thin, nyloc, castellated…..
Heavy hex nuts are slightly larger and thicker than standard finished hex nuts. There are numerous grades and the heavy pattern is typically used for large diameter and high strength bolts. See our nut compatibility chart to determine the compatible heavy hex nut s for a specific grade of bolt. Since hot-dip galvanizing typically adds 2. Quick Quote.

Bolt & Nuts Dimensions
A screw and a bolt see Differentiation between bolt and screw below are similar types of fastener typically made of metal, and characterized by a helical ridge, known as a male thread external thread. Screws and bolts are used to fasten materials by the engagement of the screw thread with a similar female thread internal thread in the matching part. Screws are often self-threading also known as self-tapping where the thread cuts into the material when the screw is turned, creating an internal thread that helps pull fastened materials together and prevent pull-out.
Hex bolts from ITA Fasteners are mostly used in repair and construction work. As the name implies, they have a hexagonal head and come with machine threads for a firm and rough handling. They come in a wide range of different hex bolt sizes for custom applications depending on its dimensional requirements. Depending on the length of the bolt, it can come with standard threading or full threading.
By design, the bolt and nut will not bind up even at these worst case diameters. On: May 10, Bolt, Nut and Screw Charts. This chart is available for referencing U-bolt lengths. It is estimated that over 90 percent of inch fastener series in Canada and

Types of Bolts
Fasteners come in many different forms. Scroll down to learn about many different types of nuts, bolts and screws! Screws use their threads to provide their own holding power. The terms in the industry are commonly mixed so sometimes you will see something that is called a screw or a bolt that is actually the opposite. Example: Lag Bolts and Lag Screws are the same thing. We have broken them down according to their true definition. The square section under the head grips into the part being fastened preventing the bolt from turning when the nut is tightened.
