[Underlined] Process Check on Screwed Work to Inspection Instruction A.9. [/underlined]

[Underlined] ‘B’ Shop Group. [/underlined]
[Underlined] 25/3/43. [/underlined]

Very little screwed work is at present being done, as all gauges have been returned to the Coventry Tool Co. for re-grinding and re-adjustment.
Whilst the gauges are away, any small urgent order for screwed work is being taken to other shops for inspection.
Since the previous month’s check, the system of re-screwing salvage bolts has been stopped.
The only screwed work available for checking was:-

3/8” B.S.F. H.T. Steel Bolts for U/C 5284/B11.

The Wickman Caliper gauge was borrowed from H2 Shop, and all were found satisfactory to gauge and drawings.
