What is the minimum recommended penetration for a nail?

The nail should penetrate the member holding the point by at least two-thirds of its length, or the full thickness of the part, whichever is less (Clause 5.3).

What is the minimum distance a nail should be from the end of a timber piece?

The minimum end distance should be 12 times the diameter of the nail (Clause 5.2.2).

What is clinching and when is it used?

Clinching is the practice of bending the protruding point of a nail. It is recommended for sheathing not more than 25 mm thick to increase the rigidity and strength of the container (Clause 5.4).

What type of nails are specified?

The code refers to wire nails as per IS 723 (Clause 4.1).

This standard provides guidelines for the proper nailing of large framed wooden containers used for packaging and transportation. It covers aspects like nail selection, spacing, end/edge distances, and nailing patterns to ensure the structural integrity of the container during handling and transit. The focus is on creating durable and robust joints for framed timber crates.

Practical Notes

The code was reaffirmed in 2017, confirming its continued relevance for timber packaging specifications.

To prevent splitting in hardwoods or when nailing near edges, pre-drilling holes with a diameter slightly smaller than the nail shank is recommended.

Clinching (bending over the pointed end of the nail) should be done across the grain of the wood for maximum withdrawal resistance.
