The same fold should be put onto the top or the bottom, the front or the rear of the foam as the cover is moved into place. Parts of the rear fold can move out of position. To locate a fold that is out of position, feel along the seam edges after the cover is installed. Adjust the fold with a sharp pointed awl. Move the point of the awl 1/4 to 3/8 inch (6.35 to 9.63 mm) into the material along the seam fold. Move the awl handle to catch the seam fold and move it into position.
CAUTION:  DO NOT PUSH THE POINT OF THE AWL INTO THE FOAM BECAUSE IT WILL    DAMAGE THE CUSHION.
When attaching the hook-and-pile tape, align the edges so the cover is smooth. The hook-and- pile tape will not be seen when it is correctly attached.

Torque Tables

A. Threaded Fastener Torque Ranges
When specific torque values are not shown on the applicable drawing, use the torque values in Table 8001 as a guide for tightening nuts, studs, bolts, and screws. When tightening a nut and bolt that are used together, measure the torque value on the nut. If the nut is inaccessible or a nut is not used, measure the torque on the bolt.
(1) Standards and Specifications for Values
(a) Self-Locking Fasteners
Compared to a standard fastener, a self-locking fastener supplies more resistance when it is turned on a thread. Because of this, add the prevailing torque value to the standard torque value to get the correct torque value for a self-locking fastener. This helps prevent unwanted vibrations that can work the fastener loose. (See Table 8001.)
NOTE:  The prevailing torque value is taken from IFI 100/107, Prevailing-Torque Type Steel Hex Nuts, Grade B, Industrial Fasteners Institute, 1987. B/E Aerospace supplied the values for Self-Locking Fasteners, sizes 4-40 and 6-32.
(b) Standard Fastener Values
For any fastener not listed in Table 8001, refer to the Standard Aircraft Handbook.
NOTE:  B/E Aerospace supplied the values for Standard Fasteners, sizes 4-40 and 6-32.
