RS PRO Plain Button Stainless Steel Tamper Proof Security Screw, M4 x 20 mm
Want a strong threaded fastener that securely connects objects or attaches them to surfaces and walls? This RS PRO security screw includes a pin that's the only tool that can unscrew and screw it. This allows you to safeguard and affix items you want to prevent from being stolen or moved.
The metric thread ensures the screw forms a secure and tight attachment to a surface or object. Its A2 stainless steel material means the screw has chromium and nickel in its composition. This increases its longevity and makes it resistant to oxidation and corrosion, as well as organic and inorganic solutions and foodstuffs.
As this product complies with Restriction of Hazardous Substances (RoHS) standards, it contains only minimal levels of harmful materials. You can use this screw for fixtures that are subject to fluctuating temperatures and moist conditions.
