Teks ® Metal Fasteners are the original self-drilling screws developed to drill, tap, and fasten metal in one motion. 1. Some of our calculators and applications let you save application data to your local computer. LSL wood-to-wood applications that require 4 1/2", 5", 6" and 8" SDS screws … Table 1 provides screw descriptions (size, tpi, length), nominal diameters, head style, head diameters, point style, drilling capacities and length of load-bearing area. Edge Distance - Shear: 3/16: 2-1/4: 1-1/8.70. Permissible lateral load-carrying capacities The permissible lateral load-carrying capacity of TimberLok fasteners can be evaluated for any combination of wood member thickness using Annex G of BS5268-2, based on the following parameters: • A screw … Deck Dead Load = 10 psf Table 3 (wet-use in- service) RSS 5/16 x 4" Joist span 6 ft 8 ft 10 ft 12 ft 14 ft Live load (psf) Wood Species Screw Shear Capacity Screw Spacing in inches/ wet-use in- … Total withdrawal load is based on actual thread penetration into the main member. ... there is no appreciable increase in strength. 156 0 obj <>stream Ultimate Load - A load that during a controlled test, produced complete failure of the fastener. machine screws cheese head as per is 1366-2002: approximate weight in kgs for 100 nos. 2. 5 The screw diameters in the table above are available in head styles of pan, hex washer, pancake, lat, wafer and bugle.

Engineering data for our acme lead screws & lead screw nuts. 1/4: 4: 2.… One of the most important aspects that can affect the quality of the screw … Shear is not part of any industry standard and the values presented below are estimations based on 60% of the ultimate tensile strengths. NOTE: 1. … On the other hand, a weaker screw might buckle under the pressure, causing them to shear off. Allowable withdrawal load for DF/SP/SCL is 172 lb./in. When the bolt is subjected to shear load, also use a dowel pin. Spacing between Anchors - Tension: 3/16: 3: 1-1/2.73. Grade 2 - Low Carbon Steel - up to 3/4" proof load 55000 psi, minimum tensile strength 74000 psi - 3/4" - 1/1/2" proof load 33000 psi, minimum tensile strength 66000 psi; Grade 5 - Medium Carbon Steel, Quenched and Tempered - up to 1" proof load 85000 psi - 1" - 1/1/2" proof load … 4 ANSI/ASME standard screw diameters were used in the calculations and are listed in the tables.

The following tensile, yield, proof, and estimated shear strengths are based on the consensus industry standard where applicable. Column Loading Capacities Chart. Screws may be provided with the 4CUT™ or Type-17 point. 4 Tension strength for #8, #10, #12, and 1/4" screws must be … and for SPF/HF withdrawal is 121 lb./in. Once the applied load has exceeded the first thread's capacity… Reducing the flight pitch reduces the capacity. (except for drywall screws, which are brittle) Most hanger failures are because the screw didn't get a good grip or because the load gets yanked from several directions and it slowly enlarges the screw … Google use cookies for serving our ads and handling visitor statistics. Wire eye bolts should never be used with angular lifts.
