Don Reid wrote back in 2007 that the WAF bolts function better as a single
bolt in double shear top & bottom (2 total) than 2 on each fitting, forward
and aft, top & bottom (4 total). I know that KRs fly in both configurations.
My KR used 4 per side when I got it and (partially based upon Don's wel
Nobody's shown me a torque for KR wing attach fittings. It's not in the
plans. Why is that? Because friction was not even considered in the
analysis of the wing attach joint. It was a pure shear calculation.
It's simply a pinned joint, and safe enough on that basis alone.
Although I'm certai

Ignoring clamping friction in a bolted shear joint calculation seems to be a
worst case analysis in that the assumption is: the bolts are torqued just
enough to keep from rattling around. The total load then would be applied
in shear to the bolt. That assumption does not seem realistic for pra
Torque is only for keeping the nuts from backing off...it is much better
than lockouts.

No one in their right mind would deliberately put a shear joint
assembly together without proper torqueing on the bolts.
Streamlined flying wires are installed in exactly that manner, with a
clevis pin, not a bolt, in shear bearing the tension load of the wire.
The clevis pin is retained by
