Pin-In-Hex Socket Screws feature a small metal post in the middle of the screw head that prevents a normal hex driver from engaging. Available in stainless steel in both machine screw and sheet metal scew styles. Pin-In-Hex Socket screws can only be installed with the correct security bit or key.
CSFI can engineer the ideal tamper proof/security screws according to your exact specifications. CSFI offers you unprecedented protection against internal/external leaks. The screws effectively seal in or seal out air, gas, water and other substances. You can customize the screw and O-ring material, as well as the screw threading, such that all the features fit your specific application. CSFI engineers socket tamper proof, spanner, 6-lobe tamper proof and one way slotted screws. Our fasteners are ready to use with no installation preparation, and can be reused for years. They are compatible with all surface types and act as a total deterrent against external/internal contamination from air, water, gas, and other harsh environments when you use compatible "O" ring materials. As a result, you can count on them in every situation.
