Finally, test for continuity with a multimeter. If you are not getting continuity, check to see if there is silicone between the pan head of the screw and the washer and screen. As mentioned above, silicone will insulate the connection and the current will not flow. If you apply glue as neatly as possible in the first place, there shouldn t be any problems. 

Predicted failure probabilities for these bolts has risen to 8.3% It therefore seems prudent to try to confirm these predictions ere equipment can- be easily positioned, used and retrieved If problems occur. Confirmation of these failure probabilities could be used as an argument for other socket headed screws within the charge pan structure which have lower predicted failure probabilities, less redundancy. In fixing, but greater associated risk. 

Machine screws are generally used with threaded inserts, nuts, and clips. They rarely are used in pretapped holes. Particular attention should be paid to the head of the fastener. Conical heads produce undesirable tensile stresses and should not be used. Bolt or screw heads with a flat underside, such as pan heads, round heads, and so forth (Fig. 7.7), are preferred, because the stress produced is more compressive.

Socket head cap screws removed from a section of charge pan In the Oldbury test well exhibited non standard features in the socket The method of forming the socket is shown diagramatically In Fig. 5 Reference to the British Standard 2470, showed that socket depth was not defined and varied considerably from manufacturer to manufacturer However using the test well bolts as the best pattern available SWR SSD carried out a considerable number of tests and a review of relevant ultrasonic testing techniques (Ref. 5).
