Frequently Asked Questions
What is a through hole screw used for?
Through hole screws are hollow full-thread penetrating fasteners, mainly used for special assembly scenarios requiring wire routing, pipeline penetration and through-type locking fixation for precision equipment.
What is the difference between through hole screw and ordinary screw?
Different from solid ordinary screws, through bore screws have hollow penetrating structure and full-through thread, supporting special functional assembly such as line passing and ventilation, with wider application flexibility.
Can you make non-standard custom through hole screws?
Yes, we provide one-stop custom machining for special inner hole size, thread specification, length and irregular structural through hole screws.
What materials are available for through hole screws?
We support carbon steel, stainless steel, brass and other materials, with various surface treatments for anti-rust and anti-corrosion requirements.
