❓ FAQs – Dual‑Material Hand Screws
🔸 What are the typical applications for these hand screws?
They are widely used for 3D printer bed leveling knobs, camera rig quick‑release plates, PC case thumbscrews, electronic enclosure fasteners, machinery access panels, and any application where tool‑less hand tightening is convenient.
🔸 How is thread length measured? What lengths are available?
Thread length is measured from the underside of the head to the tip (head not included). We offer many standard lengths – please select from the dropdown options. If you don't see your required length, contact us – we can custom‑make most lengths.
🔸 Are these screws fully threaded? What are the thread pitches?
Yes – fully threaded from under the head to the tip. Pitches are standard metric coarse: M3x0.5, M3.5x0.6, M4x0.7, M5x0.8, M6x1.0.
🔸 Will the anodized color fade or wear off?
Anodizing creates a durable, bonded oxide layer. It will not peel like paint. Under normal hand use, the color will remain vibrant for years. Heavy abrasion may wear the finish, but typical thumb screw applications are gentle.
🔸 Can I use these screws with nuts, or are they for tapped holes only?
These are standard machine screws – they work with matching metric nuts (M3–M6) or in pre‑tapped holes. For through‑hole applications, use a nut on the back side. The knurled head is for hand grip only – do not use tools on the knurling.
🔸 Are these screws magnetic?
The aluminum head is non‑magnetic. The stainless steel thread may be slightly magnetic depending on cold working, but overall magnetic interference is very low – safe for most electronics.
