Slotted pan head machine screws are made of corrosion-resistant metals for long lasting durability and dependability.
Build Your Part
Our cap screws, like our machine screws, are designed to block in/out fluids, air, and chemical contaminants.

Hexalobular (6-Lobe) cap screws, have a sixlobe recess and are driven using a 6-Lobe wrench or insert bit, making them more efficient than slotted screws and hex drives screws.
Build Your Part
CSFI’s hex sealing bolts are designed to withstand extreme pressure, and to form a complete seal along the threading of your bolt.

Where harsh climates attack, CSFI protects. Where pressure from water or gas threatens, CSFI defends. Introducing CSFI’s exceptional line of self-sealing screws, bolts and nuts. Designed for ultimate deterrence and for the roughest conditions, these self-sealing fasteners will create unbeatable fortification for your equipment.
An ordinary screw lacks adequate seal protection, allowing contaminates such as dirt or water to infiltrate and destroy sensitive devices. CSFI has engineered a solution to this problem with its exceptional line of sealing screws, bolts, and nuts. Although our hardware is just as easy to use as ordinary products, the upgraded results you will see are unique to CSFI’s hardware alone.
CSFI’s smart, aesthetic design incorporates a rubber O-ring under each nut, screw, or bolt head, thus granting both insurmountable sealing and fastening power to the fastener while providing metal-to-metal contact. Our resilient, malleable O-ring fits with tight precision under the screw, bolt, or rivet head, forming a sealant layer between the fastener and any type of harsh environment. Our seal fasteners are designed for bi-directional sealing, thus offering protection in all directions (axially, radially, angularly). They are also very easy to use, as they don’t necessitate any special preparation or re-tightening.
CSFI sealing screws are available in a wide range of screw materials as well as O-ring material options. Click on the links below for assistance on how to choose the right materials for your specific application:
CSFI seal screws, bolts, and nuts are dependably resistant against the chemical and environmental elements ordinary fasters don’t stand a chance against. They are user-friendly, cost-effective solutions to any challenge you may face in the field, in the water, in the operating room, and beyond. Whether you’re building from scratch or in need of enhancing your equipment, CSFI will have a high functioning sealing screw, bolt, or rivet to meet your every requirement.
