MIL-DTL-2427 Box, Ammunition Packing: Wood, NailedThis specification covers three types and nine classes of basic box designs having two exterior vertical cleats on each end as shown in figure 1. Also, it covers the closing and strapping requirements for filled boxes \(see Appendix A\), and prescribe the criteria to be utilized to determine the serviceability of Government furnished boxes \(see Appendix B\). The box may or may not have hinge and hasp hardware, rope handles and double end construction.

MIL-DTL-2427H (AR)

Staples may be driven in a single row and from the board into the cleats. Staple legs shall

be spread and the points clinched. Staples shall be made from 14 gauge wire.

b. Cleats may also be fastened with automatically driven wire having a knurled or

screw type surface in lieu of the nails or staples specified above. The fasteners shall be

headed and clinched. The wire used shall be 13 gauge. The number of fasteners used

shall be 1 1/2 times the number of nails required. Basic nailing requirements shall be

followed except that the spacing shall be decreased to provide a uniform pattern

(see

6.5)

3.8 Fabrication and tolerancing.

3.8.1 Fabrication. All parts of the box shall be cut square to size and of uniform

thickness. The grain in the wood shall be located in the direction providing greatest box

strength; that is, lengthwise for sides, tops and bottom, crosswise for ends or as shown in

Fig. 8 for double ends, lengthwise in cleats. Top and bottom edges shall be flush with the

outer edges of sides and ends. Sides shall extend to cover the full thickness of ends and

end cleats. End cleats shall be cut lengthwise to come within 1/8 inch of the outer surface

of tops and bottoms. End cleats shall be positioned so that sides will fit flush against

them. Top cleats shall be cut lengthwise to come within 1/8 inch of the top edges.

Hardware shall be securely attached with screws fully seated but not over driven so that

they continue to turn freely. Nails shall be driven so that neither the head nor the point

will project above the surface of the wood. Occasional overdriving of nails will be

permitted but no nail shall be overdriven more than .125 inches below board durface. The

points of clinched nails shall be driven flush or below flush and any remaining exposed

portion of the nail shall be smooth. All boxes shall be clean, uniform in appearance and

free of splinters. When two nails are occasionally driven coincidentally in the same

location, the nails shall be acceptable as long as the integrity of the box is not affected

(splitting terminating in edge of box).

3.8.2 Tolerancing. The following dimensional allowances and tolerances will

apply when not otherwise specifically stated:

a. Mismatch of boards in a panel

(variation of thickness in

adjacent boards)

= 1/16 inch max.

b. Variation in thickness in a

set of cleats, i.e., all top

cleats, all end cleats

= 1/16 inch max.

c. Variation due to crook in board �

(1) Gap between adjacent

boards; must butt at

some point

= 1/4 inch max.
