Fastener Installation in Cost Report

[peterPan]

Hi, the Processes Table contains the following items for fastener installation amongst others:

Power Tool <= 25.4 mm
Power Tool <= 6.35 mm
Power Tool > 25.4 mm
Ratchet <= 25.4 mm
Ratchet <= 6.35 mm
Ratchet > 25.4 mm

What does the dimension refer to? Diameter of the Bolt or the Bolt head? Diameter of the tool (bit, nut) used to install the fastener? Fastener Engagement Length?

Regards, peterPan

Question for $200: what's the "standard" way for specifying fastener size?

[deepakspringy]

I agree that fastener size is specified by the diameter of the bolt but if you see here cost shouldn't matter by whether you are tightening a 6mm bolt or a 10mm bolt, rather it would depend on the engagement length. So I think we should use fastener engagement length.
