⚙️ Product Overview: M3–M6 Pozi Pan Head Machine Screws – Nickel Plated Steel
If you’re tired of Phillips drivers slipping out just as you’re about to tighten a screw, switch to Pozidriv. These M3, M4, M5, and M6 Pozi pan head machine screws feature the Pozidrive (Pozi) recess – designed to give you better bite and significantly less cam‑out than standard Phillips. Made from steel with a bright nickel plating, they offer good corrosion resistance and a clean, polished finish that looks great on appliances, furniture, and automotive trim. Fully threaded with coarse metric pitch, these bolts are perfect for machinery, electronics enclosures, and DIY projects where a reliable, non‑slipping drive is a must. Length is measured under the head – select what you need.
✨ Why Choose Nickel Plated Pozi Pan Head Screws
-
Pozidriv (Pozi) drive – Distinct from Phillips, the extra cross‑recesses provide greater torque transfer and reduce cam‑out. Your driver stays engaged, even under load.
-
Nickel plated steel – Bright, corrosion‑resistant finish. Protects against rust and gives a professional, polished look.
-
Pan head design – Low‑profile rounded head with a flat bearing surface. Distributes clamping force evenly and sits neatly on surfaces.
-
Metric sizes M3, M4, M5, M6 – Covers the most common medium diameters for appliances, furniture, automotive, and industrial use.
-
Fully threaded, coarse pitch – Threads run the entire shank length. M3x0.5, M4x0.7, M5x0.8, M6x1.0. Maximum grip in thin materials.
-
Length measured under the head – No confusion: an M5 x 20mm screw has 20mm of threaded shank below the pan head.
-
Grade 4.8 strength – Reliable for general fastening in machinery, furniture, and light structural applications.
-
Brand: GooBetter, made in China – Consistent quality at an affordable price.

❓ FAQs – Pozi Pan Head Nickel Plated Screws (M3–M6)
🔸 What’s the difference between Pozidriv and Phillips? What driver bit do I need?
Pozidriv has additional smaller cross‑recesses at 45° angles and a blunter tip. A Phillips driver will fit loosely and will cam‑out or damage the recess. For M3 and M4, use a PZ1 Pozi driver. For M5 and M6, use a PZ2. Using the correct bit gives you much better torque without slipping.
🔸 Are these screws fully threaded? How is length measured?
Yes – they are fully threaded from just under the head to the tip. Length is measured from the underside of the head (the flat bearing surface) to the tip, not including the pan head. For example, an M5 x 20mm screw has a 20mm threaded shank below the head.
🔸 Will nickel plating rust or wear off?
Nickel plating provides good corrosion resistance for indoor use and light outdoor exposure. With repeated driving, the recess and thread tips may show some wear, but the overall finish holds up well for most DIY and industrial applications. For constant wet conditions, consider stainless steel.
🔸 Can I use these screws with nuts, or are they self‑tapping?
These are machine screws – they require a matching metric nut (M3–M6) or a pre‑tapped hole. They are not self‑tapping. For best results, pair them with standard metric nuts.
🔸 What lengths are available for each diameter?
Lengths vary – please select from the dropdown options on the product page. Typical ranges: M3 (4–30mm), M4 (5–40mm), M5 (6–50mm), M6 (8–60mm). All lengths are measured under the head.
🔸 Are these screws magnetic?
Yes – the steel core is magnetic. For most applications, that's not an issue. If you need non‑magnetic fasteners for sensitive electronics, consider brass or nylon.
