CSFI’s line of self-sealing screws, bolts, and nuts offers you unsurpassable fastening and sealing power. Each of our fasteners is equipped with a unique, malleable and strong captive O-ring. This device delivers extraordinary results. The O-ring, which fits tightly and precisely in the groove under the screw/bolt/rivet head, acts as a total deterrent against external/internal contamination from air, water, gas and other materials. As a result, your screws and bolts will perform like never before, granting your most sensitive equipment unbeatable protection with 360 degrees of sealant while achieving metal-to-metal contact.
Our screws and bolts are ready-to-use and can be installed the same way as their conventional counterparts. They are also reusable, and can be used with all surface types and in any environment which exposes them to a variety of conditions when you use a compatible O-ring material. Moreover, in the case of high-level vibration, we can fasten self-locking strips, pellets and patches on to your screws or bolts for full shock-absorbency. CSFI offers clients complete customization–from thread styles to headpiece options to driver types. Your needs are completely met, and your expectations fully exceeded.
When you’re up against harsh environments, CSFI’s line of self-sealing nuts guarantees you unsurpassable fastening and sealing power.

When it comes to sealing and protecting switches, CSFI has established itself as a global leader. When it comes to customer satisfaction and cost-efficiency, CSFI stands at the top.
CSFI’s switch boots feature elegant, flexible, and highly effective switch protection. CSFI’s switch boots are crafted from a single piece design of molded rubber over a brass hex nut. The boots can be custom fitted for a variety of electronic devices that are exposed to the elements. CSFI has engineered the optimal switch boot using a combination of silicone, brass and other materials. Small and lightweight, they will operate in temperature ranges from -93 degrees to 400 degrees Fahrenheit. Our team of technicians uses cutting-edge methods and equipment to test, re-compound and mix materials to create an elastomer, which is then molded to fit specifications. As a result of our superior craftsmanship, our coverings, suited to transfer mechanical energy, create absolute seals while providing full flexibility. They are also reusable and can be customized according to shape, thickness, weight, and color requirements. The boots conform to military specifications and are DFARS and ROHS compliant.
CSFI is one of the very few companies that supplies self-sealing specialty screws. If you’re making the investment in advanced equipment that requires specialty screws, then your next investment should be in CSFI’s powerful self-sealing specialty screws, which can handle any environment with their captive O-ring design. The O-ring seals the screw, creating a complete barrier against external forces such as water or dirt. If you’re using ordinary screws then your equipment may be significantly more susceptible to damage.
