Your deck will depend on the load-carrying capacity of these screws or bolts to support hundreds of pounds and prevent the deck from ripping away from the house. The ability of a screw to resist stripping or axial extraction (pulling out the threads) is really a function of the wood itself. Glulam is commonly used in post and beam, heavy timber and mass timber structures, as well as wood bridges. Simpson makes screws approved for many straps and anchoring uses - and those screws bend like nails. 1C refers to the same 1. Also known as screwbolts. From tiny cracks come big failures! Short, shallow-threaded wood screws don’t hold well in the edge of composite wood. This calculates to 625 lbs and 500 lbs respectively. The large washer head gives high head pull-through resistance while allowing the timber members to close up firmly. Introduction In the manufactured housing industry, one of the principle uses of lag screws is the connection of the wood-frame house to the transportation chassis. 2 of NDS-15 (Section 10.

If you are calculating the stress on a threaded section of bolt, you will need to specify the number of threads per inch below. Internal drive screws with a slot and currently and far more commonly a Pozi® or Phillips® drive. Available Sizes (Lengths) #10 x 1 1/2″ Screws for Steel Furring. Another option is to use wood screws in place of nails because they tend to have higher withdrawal capacities. On the other hand, thread-cutting screws are typically used for wood and metal, literally removing some of the material and creating a threaded path for the screw. Shear values for parallel application exceed those for perpendicular application, 3. AS 4100 does not express stress values but extends the data to a “Design Resistance Capacity” taking account of the length of the joint (see Table 12 Note 2), the available bolt shear area (threads or shanks) and a “Capacity Factor” which is 0. However, some electrically operated 2. A single angle iron that size screwed into solid wood or other solid material can support 3. The USP head stamp identifies the screw length for easy inspection. #N#Machine Screw Sizes. One or two step threaded rod attachment. Load was applied to the screws until the fastener pulled out of the slot. Ensures correct installation torque. When working with wood, consider using a washer if the bolt is longer than the width of the timber being secured as the head of the coach bolt could damage the joint and reduce load capacity. The diameter of a screw is measured on the smooth part of the shank, or the outer edge of the thread, and ranges from 6mm to 20mm for coach screws, and from 4mm to 8mm for countersunk screws. , Reinhardt HW. A total of 79 tests were conducted, as summarized in Table II. " these are essentially really thick screws. The thickness of the steel sheets ranged from Gauge 24 (0.
