CSFI socket cap seal screws are widely used for their larger head height, resulting in a stronger part, which permits use of a higher torque value. They are engineered with a rubber O-ring under the head of the screw, that once tightened, squeezes outwardly to form a 360° leak-proof seal. This impenetrable, unbreakable seal prevents contaminants, i.e. water, oil, gas, fluids, precipitation, saltwater, dust, moisture and more, from entering and damaging equipment or leaking out and potentially harming our environment.
CSFI socket cap seal screws have unmatched gripping ability and reduced stripping. Equipment applications include: Air tooling, generators, pumps, compressors, machine parts, automotive components, and electronic devices. Available in corrosion-resistant metals and can withstand extreme pressure, vibration, temperatures (hot & cold) & weather. Made in the USA/Buy American Act compliant.
