Carriage bolts round head with square neck are commonly used in wood connections The square neck under the round head will seat into the hole in the wood to prevent the head from turning Because they are used with wood carriage bolts are rarely high strength and virtually always supplied in a standard ASTM A specification Manufacturing Jan 21 A carriage bolt is a type of fastener that can be made from a number of different materials stainless steel being the most popular A carriage bolt generally has a round head and a flat tip and is threaded along part of its shank Carriage bolts are often referred to as plow bolts or coach bolts and are most commonly used in wood applications 5/16in x 1 1/4in galvanized carriage bolt are used to secure an assortment of chain link fence fittings and accessories such as rail ends tension bands brace bands and gate hinges to fence posts The bolts feature a galvanized coating to help prevent rusting and corrosion and added longevity Includes 20 carriage bolts and nuts View MoreCOLIBROX 4pk Carriage Bolts Nuts for A Shave Plate Scraper Bar 5/16 18 5/8" 4 7 out of 5 stars 8 95 Get it as soon as Mon Aug 9 One of the greatest problems associated with fillet welded joints is achieving the correct weld size in relation to the required leg lengths or throat thickness Fig 4 The designer may calculate the size and allow a & 39 safety factor& 39 so that the weld specified on the fabrication drawing is larger than is required by design considerations Head diameter is roughly twice the size of the bolt or for smaller sizes a little more than double The width across flats of the square neck is about the size of the bolt Table 1 lists head diameter and height and square neck width and depth Grades 2 and 5 steel and stainless steel are the most prevalent types of carriage bolts Structural Bolts ASTM A AM A and AM structural bolts from % domestically melted and rolled material with certifications provided from our A2lA accredited laboratory Structural Nuts Nucor makes ASTM A Heavy Hex Structural Nuts from ½” to 1” sizes in Grades C C3 DH DH3 from % made in the uSA materials Retainer weld nuts also known as bridge weld nuts or floating cage nuts have a floating nut held within a " cage" or retainer to allow off center or misaligned screws to be installed The retainer itself is welded to a workpiece while the nut is allowed to float freely and help compensate for building inconsistencies Aug 21 fillet weld for the full length of the plate If the plates are different thicknesses the thinner plate thickness should be used An example t joint is shown below with a weld size of 3/8" on 1/2

Heavy Duty Ferrules The ferrule helps to shield the arc from the operator it minimizes the atmosphere that the flux must purge the ferrule helps form the molten metal into the fillet while allowing the fillet vents allow weld gases to escape Ferrules are disposable items and as disposable items they are mass manufactured quickly and inexpensively Ferrules are …Cap Screw Fasteners A cap screw is a screw that has a thick wide head and a flat bottom toward the thread facing site The hex head cap screw is the most common cap screw and is also the most common fastener in construction and machine assembly Our cap screws can be customized to your application and industry Weld Nut with a Floating Cage Nut for Misaligned Holes Retainer weld nuts also known as bridge weld nuts or floating cage nuts have a floating nut held within a " cage" or retainer to allow off center or misaligned screws to be installed The retainer itself is welded to a workpiece while the nut is allowed to float freely and help compensate Typically carriage bolt sizes range from 10 to 3/4" in diameter while lengths span from about 1/2" to 20" —only larger sizes are available in long lengths Measure length from under the head to the threaded end of the bolt Head diameter is roughly twice the size of the bolt or for smaller sizes a little more than double Lag & Carriage Bolts Carriage Bolts come with a round head and a square neck are commonly used in wood connections The square neck under the round head allows the bolt to set into the hole in the wood to prevent the head from turning Carriage Bolts are generally manufactured to the A Grade A specification in domestic or import Bolts oGeneral oDesign resistance of individual fasteners oNon preloading bolts oSlotted holes oDesign for block tearing oWorked examples oSummary Welds o General o Fillet weld o Design model o Design example o Welding to flexible plate o Summary Column bases o Basis of design o Components o Base plate and concrete in compressionGrind flush the ends of the two 1/4" x 20 x 1" carriage bolts Then weld the two carriage bolts together being sure to use filler metal The complete bolt assembly will be 2" in length Since most bolts are cadmium plated allow for proper ventilation for this particular weld or remove the plating prior to welding Carriage bolts have a domed head and feature either a square or ribbed neck that prevents turning during and after tightening They are used for fastening both wood and metal Carriage bolts

Carriage Bolts Round Head Ribbed Neck Length of a carriage bolt is measured from the underhead bearing surface to the extreme end of the bolt Tolerance on 10 through 1/2" sizes for nominal lengths of 7/8" and shorter shall be and Carriage bolts have a smooth rounded head for a finished look The square neck keeps these bolts from turning when tightening a nut Made from Grade 8 steel these bolts can be used in high stress applications such as valves pumps motors and automotive suspension systems Carriage bolts have a smooth rounded head for a finished look The basis of most methods of calculating fillet weld strength is the assumption that the key dimension defining the load carrying capacity of the weld is the throat size A feature of overload failures of fillet welds is that in many of them the fracture is along their plane of fusion to one or other of the two members being joined and very 1/2 in 13 x 8 in Galvanized Carriage Bolt 25 Pack Carriage bolts have a smooth rounded head Carriage bolts have a smooth rounded head with a square neck underneath that locks into wood when tightened Use with a pre drilled hole and secure with a hex nut and washer to prevent spinning ASTM A Structrual Bolts Alloy Steel Heat Treated ksi Minimum Tensile Strength Nuts and washers used in a structural joint with heavy hex structural bolts must also meet appropriate standards Falling under ASME B18 2 6 dimensional standard there are two chemical and mechanical designations for structural nuts ASTM A and A Static Strength of Welds FFNormal = Shear = F w h F w h 2F F F 1/8 75o 3/8 1/4 Max Normal = Max Shear = F w h F w h Butt Fillet h = throat size!
