How do you level a floor by Sistering joists? via dimple nail holes. Box nail - like a common nail but with a thinner shank and head ; Brads are small, thin, tapered, nails with a lip or projection to one side rather than a full head or a small finish nail 2, the diameter of the nail at the shear plane becomes a critical factor in the lateral yield strength of the nail. 0000041719 00000 n The nail length and diameter are key factors in determining the strength of nailed connections in wood framing. Metal Strength Properties Shear Strength – Lbs needed to slice metal Approx 1,500 Lbs * #8 deck screw Tensile Strength – Lbs to stretch until break metal Approx 2,500 Lbs * Bending Yield – Lbs to bend metal beyond elastic Approx 125,000 psi * Used to compare fasteners only where: α v is a coefficient that takes values α v = 0.6 for bolt classes 4.6, 5.6, 8.8 or α v = 0.5 for bolt classes 4.8, 5.8, 6.8 and 10.9. The diameter for a 10d common nail is 0.148 inch; thus the required penetration for full capacity of the connection was taken as: 11 x 0.148 inch = 1.628 inches which rounds to 1-5/8 inches. And it would follow suit that one hundred 2-inch (or 6d) nails cost, well, 6 pennies. 0000008006 00000 n 0000004706 00000 n Sizes of ... ch07.pdf. 112 lb: Not listed in table. Provides users with a web-based approach to calculating capacities for single bolts, nails, lag screws and wood screws per the 2015 NDS. place for positive seating and nailing ease Diamond holes (no need to fill unless otherwise noted) 10d x 1-1/2 (0.148" x 1-1/2") 8d x 1-1/2 (0.131" x 1-1/2") 0.88 446 0 obj <>stream indicates that shear strength is likely a better indicator of with-drawal strength than is specific gravity.
