10.17.3 Approximate hardware weights
The information below lists calculated weights of both coarse thread (UNC) and fine
thread (UNF) bolts. This is very useful in any balancing procedure when you use bolts to
add balance weight.
Weights are calculated for the following bolt hardware:
• Hex head cap screws
• Socket head cap screws
• Machine screws
• Socket head set screws
All weights are in ounces. Where applicable, the weight of nuts, flat washers, lock washers,
and the bolt head are also given. Weights given in tables are for steel hardware. To find
weights for hardware of other materials:
