Question 1047318
The way I read it:
each screw is 1 5/8" long + 1/8" for finishing, so in raw form the bar stock for each screw is 1 5/8+1/8 = 1 6/8 = 1 3/4 = 1.75
And we have 500 screws:
500*1.75 =  875 inches long.
Diameter: 1/2 = radius 1/4 or 0.25
Volume: Pi*0.25^2*875 = 171.81 in^3
Weight:
171.81*.311 = 53.43 lbs is the weight of the rod
