Reliable China Hi-Low Drywall Screws maufacturer
Sinsun’s Hi-Low Drywall Screws adopt an innovative high-low double thread structure (Hi-Low Thread), combining high lead (shallow groove wide pitch) and low lead (deep groove close pitch) threads in alternating arrangement, perfectly balancing the dual needs of fast entry and firm grip. Designed for efficient construction, it can reduce installation time and improve tensile strength and seismic performance. It is suitable for gypsum boards, wooden/metal keels and composite structures. It is an ideal screw choice for commercial projects and high-end home decoration.
- Double thread design, fast installation and extreme bite force
- Head design: countersunk head (82° cone angle), flat head can disperse pressure
Reduce material splitting: optimize thread pitch and depth to avoid cracking or delamination of the gypsum board surface.
Quick installation: double thread design reduces rotation resistance, installation is more labor-saving, and construction speed is increased by 30%.
Anti-slip groove design: reduce slippage and improve installation accuracy.
Anti-rust coating: galvanizing, phosphating or other coating processes,
Multiple specifications: provide a variety of lengths (such as 1-1/4 inches to 3 inches) and diameters (such as #6, #8)

Focus On Hi-Low Thread Technology
1. High-low double thread, both efficiency and strength
High lead thread (shallow groove wide pitch): quickly cut into the material, reduce rotational resistance, and increase installation speed by 30%.
Low lead thread (deep groove close pitch): densely bite the frame, and the tensile strength is 50% higher than that of ordinary single-thread screws.
Dynamic balance design: alternately arrange high and low threads to prevent screws from “slipping” or “stuck”, suitable for high-speed operation of power tools.
2. Anti-split guard plate design
Progressive thread taper: gradually increase pressure from the tip to the end of the thread, disperse stress, and reduce the risk of cracking on the gypsum board surface.
Self-limiting countersunk head: automatically stop after reaching the preset depth to avoid over-tightening and causing the board to dent.
3. Super compatibility Adapt to a variety of substrates:
Gypsum board: single-layer, double-layer or composite board with sound insulation layer.
Frame: wooden keel, light steel keel (0.5-1.2mm thickness).
Tool-friendly: compatible with cross slots (PH2), supports 3000 RPM electric screwdrivers.
4. Long-term anti-rust, durable
Galvanized + sealed coating: basic anti-rust galvanized layer (zinc layer ≥ 8μm) superimposed with transparent sealer, salt spray corrosion resistance time extended to 500 hours (ASTM B117 standard).
5. Anti-vibration and anti-loosening
Double thread locking effect: high and low threads are staggered to form multiple points of bite, and the anti-loosening performance is increased by 70% in a vibrating environment
Hi-Low Thread Drywall Screw Application
Commercial buildings: office partitions, shopping mall ceilings and other high-frequency construction scenes, shortening the construction period.
Home decoration: gypsum board TV wall, custom wardrobe, taking into account both efficiency and beauty.
Sound insulation project: fix the composite wall with sound insulation cotton to prevent long-term vibration from causing loose structure.
Outdoor semi-structure: rainproof eaves, semi-open partition (with anti-rust coating).
High thread reduces driving torque, making construction more labor-saving. Low thread increases contact surface, zero loosening due to vibration.
Recommendations for Use
Tool settings:
Set the torque of the electric screwdriver to 3-4Nm and the speed to ≤2500 RPM to avoid overheating of the thread.
When installing light steel keels, it is recommended to use magnetic guide sleeves for precise positioning.
Installation spacing:
Gypsum board edge: screw spacing ≤15cm, center position ≤30cm.
Light steel keels: cross-fix at least 2 screws per keel.
Environmental adaptation:
Galvazied coating models are preferred in high humidity areas.
It is recommended to use screws longer than 50mm for composite sound insulation walls to ensure penetration of the sound insulation layer.
FAQ
Q: Can Hi-Low threads be used on concrete substrates?
A:No! Designed for gypsum board and metal/wood frames, concrete requires anchor bolts or concrete screws.
What is the difference with traditional double thread?
Double thread only increases the penetration speed, while Hi-Low thread achieves dual optimization of speed and strength through height difference.
Does it support customized non-standard length?
Yes! Lengths above 50mm can be customized, with a minimum order quantity of 2,000 pieces
