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 "Dublock Nail" features a special reverse-rotation prevention head shape, and since it is not flexible, it does not produce burrs. As it is installed by driving, there is no "floating" between components. Additionally, screws are placed under the head, converting the force during installation into rotational force. Both the substrate and the mounting materials are secured by screws, preventing rattling and creaking due to "shrinkage of wood." Moreover, 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 ■ Certification for framed walls obtained on February 21, 2020 ■ For framed wall construction (2x4), load-bearing wall TBFC-0155 with a wall multiplier of 3.0 ■ For framed 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 during work on scaffolding or roofs ■ Fast work due to the ability to drive with a nail gun ■ As screws, the decrease in pull-out strength over time is extremely low ■ In addition to high pull-out strength, the 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 splinter wood when using flexibles, preventing burrs (splinters) ■ 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.
