Cap Sealing Screw Nyseal Sealing Bolts Security Torx Cap Head

Cap sealing screw is the screw with cap head and with the sealing ability. Nyseal is a great gasket alternative, creating a gasket-type seal, preventing leakage of fluids and gases under pressure. The coating is permanently fused on the bearing surface of the fastener. As the screw is seated to its final position against the mating part, the Nyseal element compresses slightly and fills the void between the bearing surface of the head and the counter sink/counter bore. Ever Hardware provides custom-made fasteners and customizable packaging.

Security torx is a version known as Security Torx, Tamper-Resistant Torx (often shortened to Torx TR), or pin-in Torx contains a post in the center of the head that prevents a standard Torx driver (or a straight screwdriver) from being inserted. Torx screws are commonly found on automobiles, motorcycles, bicycle brake systems (disc brakes), hard disk drives, computer systems, and consumer electronics.
An External Torx version exists, where the screw head has the shape of a Torx screwdriver bit, and a Torx socket is used to drive it. The external “E” Torx nominal sizing does not correlate to the “T” size, (e.g. an E40 socket is too large to fit an E40, while E8 Torx socket will fit a T40 Torx bit).
