About this item
- This assortment kit includes 20 pieces M4 x 20mm hex socket button head screws, matching nylon lock nuts, flat washers and 1 L-shaped hex wrench. All fasteners are manufactured from premium stainless steel, offering reliable rust and wear resistance. It effectively withstands indoor dampness and oxidation to maintain steady clamping force for long-term furniture and mechanical equipment assembly.
- The matched hex nuts are equipped with built-in nylon ring. It generates consistent friction during tightening to stop loosening triggered by vibration or frequent shaking. Paired with flat washers, pressure is evenly spread to protect contact surfaces and keep joints tight over time.
- These button head machine screws feature standard inner hex socket, fully compatible with the supplied hex wrench and common hex screwdriver bits. The smooth rounded button head distributes tightening pressure evenly and avoids sinking into wooden, plastic or metal panels, greatly boosting assembly efficiency.
- All screws, nylon lock nuts, flat washers and hex wrench are sorted separately inside a clear divided plastic storage box. Independent compartments simplify classification, transport and quick retrieval during home renovation, furniture fitting and equipment maintenance work.
- These M4 stainless steel button head screw sets are suitable for multiple fixing scenarios. Perfect for wooden furniture assembly, mechanical equipment fitting, model building, plastic product installation and general daily DIY replacement fasteners.

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.
