Drive-in screw nail "Double Lock Nail"
In addition to the high pull-out strength, the shear strength is also 1.7 times that of round nails! The screw shape converts the force during driving into rotation. This leads to an overwhelming reduction in construction time.
The "Double Lock Nail" features a special head shape that prevents reverse rotation, and since it is not flexible, it does not produce burrs. Because it is installed by driving, there is no "floating" between components. It also has screws under the head that convert the force during installation into rotational force. Both the substrate and the mounting materials are secured by screws, preventing rattling and squeaking due to "shrinkage of wood." Additionally, there are types available that can accommodate fastening to metals such as C-shaped steel, which require drill screws. 【Features (Excerpt)】 ■ Obtained Ministry of Land, Infrastructure, Transport and Tourism certification for a wall multiplier of 3.0 in 2x4 construction method ■ Certification for frame walls obtained on February 21, 2020 ■ For frame wall construction (2x4), load-bearing wall TBFC-0155 with a wall multiplier of 3.0 ■ For frame wall construction (traditional), load-bearing wall FRM-0677 with a wall multiplier of 2.5 ■ Significant reduction in construction time ■ Block nails driven by a nail gun can be installed with one hand ■ Improved safety when working on scaffolding or roofs ■ Fast work because they can be driven with a nail gun ■ As screws, the reduction in pull-out strength over time is extremely low ■ In addition to high pull-out strength, shear strength is 1.7 times that of round nails *For more details, please refer to the PDF materials or feel free to contact us.
basic information
【Other Features (Excerpt)】 ■ Flexibility that does not break even when bent at 90° ■ Can be driven to the desired depth with a nail gun ■ Does not cause splinters as it does not shave the wood with a flexible tool ■ Extremely minimal reduction in pull-out strength due to decreased elasticity of the wood ■ Special tip shape prevents wood splitting ■ Can be removed with an impact driver as a screw ■ Makes sorting after disassembly easier, and the removed double-lock nails are reusable *For more details, please refer to the PDF document or feel free to contact us.
