About this item
- 📐 M3 STAINLESS STEEL KNURLED THUMB SCREWS — FLAT OR SHOULDER HEAD — Thread M3, available in 10mm and 15mm lengths. Choose Flat Head for a flush, low-profile finish or Shoulder Head for a raised collar grip easier to grasp in recessed positions. Knurled head precision-cut for secure finger grip without tools. Available in 5 or 10 piece packs.
- 🏭 CNC MACHINED FROM SOLID STAINLESS STEEL AISI 303 — MADE IN THE EU — Every screw is precision-turned from solid Stainless Steel 303 bar stock in our European workshop. Solid stainless throughout — no coatings, no plating, no surface treatment that can chip or wear away. Superior corrosion resistance compared to coated carbon steel alternatives.
- 🔧 IDEAL FOR ENGINEERING, METALWORK, LABORATORY AND INDUSTRIAL APPLICATIONS — Designed for environments where corrosion resistance and material integrity matter: laboratory equipment, scientific instruments, industrial enclosures, marine-adjacent applications, precision metalwork, hydraulic systems and any application requiring reliable tool-free access with M3 thread.
- ✴️ TWO HEAD STYLES FOR DIFFERENT MOUNTING REQUIREMENTS — Flat Head sits flush against the surface for a clean, unobtrusive finish ideal for tight spaces and panel mounting. Shoulder Head features a raised collar that lifts the knurled grip away from the surface, making it easier to grasp in recessed or countersunk applications. Select your preferred style from the variant menu.
- ⚙️ HAND TIGHTEN IN SECONDS — COMPATIBLE WITH ALL STANDARD M3 FIXINGS — Wide knurled head delivers firm, rattle-free clamping force by hand. Fully compatible with standard M3 nuts, brass threaded inserts, stainless steel inserts and tapped holes in aluminium, steel, acrylic and wood. No tools required for installation or removal.
- 🛡️ CORROSION RESISTANT — SUITABLE FOR DEMANDING ENVIRONMENTS — Stainless Steel 303 offers excellent resistance to moisture, humidity, mild chemicals and industrial atmospheres. Unlike anodised aluminium or zinc-plated steel, these screws will not corrode, discolour or degrade with repeated use in demanding conditions.
- ✅ PRECISIONGEEK — REGISTERED EU BRAND, CONSISTENT QUALITY — PrecisionGeek specialises in CNC machined stainless steel, aluminium and brass components. Every batch is inspected for thread quality and dimensional accuracy before dispatch. Designed and machined in Europe — what you see in the listing is exactly what you receive.
- 📦 AVAILABLE IN 5 OR 10 PIECE PACKS — SELECT HEAD STYLE, LENGTH AND QUANTITY — Choose your preferred head style, thread length and pack size from the variant selector above. Supplied in a resealable pack, ready to use straight from the box. Compatible with all standard M3 threaded holes, nuts and inserts.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
