Carbon fiber gear for boaties, with a large range to choose from… All our gear uses a standard 19mm tube connector, so cross compatibility with existing products is no problem. Plus we have standard thread connectors for USA /Acme and Euro/EU which allows fitting of most other accessory brands if you already have a favorite. #deckdevil #onedesigns #detailing #yacht #boatlife #boatingnz | Deck Devil

The C clamp shown in the figure for Prob. 8-7 uses a (3)/(4) in-6 Acme thread. The frictional coefficients are 0.15 for the threads and for the collar. The collar, which in this case is the anvil striker's swivel joint, has a friction diameter of 1 in. Calculations are to be based on a maximum force of 8 lbf applied to the handle at a radius of 3 (1)/(2) in from the screw centerline. Find the clamping force. | Numerade
