How Can Security Pin Machine Screws Prevent Tampering in Electronic Assemblies?

Our flange washer head machine screws with six lobe security pin design require specialized tools for installation and removal, effectively deterring unauthorized access to sensitive electronic components. The 18 clockwise serrations under the head provide additional anti-loosening protection against vibration, while the M4x12mm 18-8 stainless steel construction ensures corrosion resistance. Contact us to receive samples and technical specifications tailored to your electronic assembly security requirements.

With 45 years of manufacturing expertise, our comprehensive inspection protocol utilizes advanced tools including calipers, protrusion-height gauges, micrometers, and 2.5D/2D projectors to verify critical measurement points such as head diameter, head height, six-lobe recess depth, pin diameter, washer diameter, serration count, thread specifications, and ring gauge GO/NO GO testing. The integrated security pin design prevents unauthorized removal while the clockwise serration pattern ensures superior grip and vibration resistance, making these machine screws ideal for applications requiring tamper-proof fastening solutions in electronics, automotive, machinery, and security equipment manufacturing.
