M6x15mm Aluminum Knurled Thumb Shoulder Screws Hand Grip Bolts Anodised 10 Color

These screws use a standard M6 metric thread with a 1.0mm pitch. This is the most common M6 pitch and is compatible with the vast majority of M6 threaded inserts, T-nuts, and tapped holes found in aluminum extrusions, steel panels, and plastic enclosures.

Yes. The knurled cylindrical head is designed specifically for hand-tightening. The knurl pattern provides enough grip for firm seating in most panel applications. For structural joints that require a specific torque value, a tool-driven M6 fastener would be more appropriate.

Anodising is an electrochemical process that converts the aluminum surface into a durable oxide layer — the color is part of the material, not a paint coat on top. Under normal hand-tightening use, the finish holds up well. Abrasive contact with hard metal tools or surfaces over many cycles may cause surface wear at contact points.

The 15mm shoulder is well-suited for panels and covers in the 1–5mm thickness range, which covers most sheet aluminum, acrylic, and thin steel enclosure panels. For thicker panels, confirm the grip length matches your stack-up before ordering.

Yes, provided you use an M6 T-nut or drop-in nut in the extrusion slot. The M6 × 1.0mm thread engages standard M6 T-nuts used in 20-series and 30-series aluminum extrusion profiles. The thumb head makes it easy to adjust and reposition panels without tools during assembly.

Absolutely. Color-coding fasteners is a practical way to mark access panels, identify subsystems, or indicate tightening sequence in complex builds. Since each color is available separately in packs of 1, 2, or 5, you can mix and match exactly the quantities you need per zone.

Order 1 pcs if you need a single replacement or are testing a color match. The 2 pcs pack suits applications with two fastener points per panel (common on small access covers). The 5 pcs pack is cost-effective for enclosures with multiple panels or when building several identical assemblies.
