Screw holding strength

Webbfactor in holding power. As a rule-of-thumb the screw diameter should be roughly 1/2 that of the shaft. Holding power is almost directly proportional to seating torque in Socket Set Screws. Hence, within the assembly's strength limits you can increase holding power by increasing seating torque. The "UNILOK" set screw's superior strength and WebbAllowable withdrawal load or force of a common wood screw into side grain perpendicular to the fibers of seasoned dry wood can be expressed as. F = 2850 SG 2 D (1) . where . F = allowable withdrawal load or force - lb per inch of penetration (lb/in). SG = specific gravity of oven dry wood D = diameter of screw (in) Note the difference between allowable load …
