DIN18182 Drill Twist-Shear Bolt with Detachable Drill Bit

Product Description

This product is a Drill Twist-Shear Bolt fully compliant with the DIN18182 international standard, engineered as an efficient connection solution for the construction and renovation industry. Its core design integrates a drill point and a shear tail structure: the drill point eliminates the need for pre-drilling, allowing direct penetration into hard materials like concrete and wood to significantly reduce construction steps; the shear tail automatically cuts through panels (such as gypsum board or PVC board) during installation, completely solving the "difficulty in penetrating panels" pain point and boosting installation efficiency by over 50%.

Made from high-quality carbon structural steel (Q235), the product undergoes black phosphating or zinc white plating surface treatment, offering excellent corrosion resistance. Black phosphating is suitable for dry environments (e.g., indoor ceilings), while zinc white plating can handle humid scenarios (e.g., bathrooms, kitchens), ensuring long-term rust-free performance. Whether for fixing gypsum board partitions in home renovations or installing lightweight walls in commercial buildings, this bolt provides stable and reliable connections, making it an ideal choice for both DIY enthusiasts and professional construction teams.

1. Core Advantages: Why Choose This Drill Twist-Shear Bolt?

1. Dual-Function Design, Time-Saving and Effortless: The combination of a drill point (no pre-drilling required, direct penetration into hard materials) and a shear tail (automatically cuts through panels) simplifies the installation process, especially for bulk projects like ceilings and partitions.
2. Detachable Drill Bit, Adaptable to Multiple Materials: The drill bit supports quick replacement (e.g., twist drills for wood, impact drills for concrete), allowing fast adaptation to any wall type. Coarse/fine threads are available—coarse threads are suitable for thick panels (≥12mm, e.g., double-layer gypsum board), while fine threads are suitable for thin panels (≤12mm, e.g., single-layer gypsum board).
3. Durable and Rust-Resistant, Longer Lifespan: The carbon steel material, combined with phosphating/zinc plating, offers far superior corrosion resistance compared to ordinary screws. It maintains stability even in humid environments, preventing connection failure due to rust.
4. Compliant with International Standards, Reliable Quality: Strictly follows the DIN18182 standard, with tested thread precision and head strength to ensure no loosening or breakage after installation.

3. Application Scenarios: Full Coverage from Home to Commercial

• Home Renovation: Gypsum board ceiling installation, partition wall fixing, cabinet/backboard connection—solves the "hard-to-penetrate panels" pain point.
• Commercial Construction: Office partition walls, hotel guest room renovations, mall decorative walls—enables fast bulk installations.
• Industrial Installation: Equipment bracket installation, lightweight metal structure fixing—uses high-strength material for structural stability.
• DIY Projects: Furniture assembly, decorative panel fixing (e.g., frames, shelves)—easily handles small-scale construction.

4. Material and Craftsmanship: Details Define Quality

• Material: Made from Q235 high-quality carbon structural steel, with a tensile strength of ≥370MPa and a yield strength of ≥235MPa, ensuring resistance to breakage during installation.
• Surface Treatment: The black phosphating process (phosphate layer ≥8μm) forms a dense protective film against oxidation; the zinc white plating (zinc layer ≥12μm) uses hot-dip galvanizing for enhanced corrosion resistance.
• Thread Precision: The cold heading forming process creates regular thread profiles for tighter engagement, improving connection stability.

5. Installation Guide: 3 Steps to Efficient Fixing

1. Choose the Right Length: Screw length = panel thickness + stud thickness (e.g., 12mm gypsum board + 38mm stud → 50mm screw).
2. Install the Drill Bit: Insert the detachable drill bit into the drill chuck and align it with the connection point (between the panel and the stud).
3. Drive the Screw: Start the drill (recommended speed: 800-1200rpm) and slowly drive the screw—the drill point will first penetrate the hard material, and the shear tail will automatically cut through the panel. Stop when the head is flush with the panel surface to avoid cracking.

6. Precautions: Tips to Avoid Pitfalls

• Avoid using non-rust-proof screws (e.g., black phosphating) in humid environments.
• Maintain a stable drill speed during driving to prevent breakage from excessive force.
• Store in a dry, ventilated place, away from corrosive substances (e.g., acids, alkalis).
• Select the correct thread type: coarse threads for thick panels, fine threads for thin panels—an incorrect choice may lead to loose connections.
