What depth should an explosive-actuated tool fastener penetrate to be considered properly set?

The correct depth of penetration for an explosive-actuated tool fastener is typically 8 to 12 times the diameter of the shank. This standard ensures that the fastener is properly secured, providing optimal strength and stability for the materials being joined. Achieving this depth allows the fastener to fully engage with the substrate, thereby distributing load and stress effectively, which is essential for maintaining structural integrity.

Tools utilizing explosive-actuated fasteners require specific penetration depth to ensure that they fulfill their intended purpose without compromising safety or performance. Fasteners that penetrate at least 8 to 12 times their shank diameter are more likely to resist pull-out forces, contributing to the longevity of the installation.

Other options, while they suggest reasonable penetration depths, may not meet industry standards for specific applications or materials. Insufficient penetration can lead to inadequate fastening, while excessive penetration is generally not necessary and may waste material or improperly secure connections.
