Cup Point Torx Pin Set Screw Wear Resistant Stable Connection Mechanical Assembly Hardware Fitting

Set screws also named grub screws are headless threaded fasteners widely used for positioning locking fixing and adjusting parts in various machinery electronic products instruments and industrial equipment. They are designed to tighten components without protruding external heads saving installation space and realizing hidden stable fixation.

Flat end set screws are suitable for flat surface positioning offering even stress and stable locking effect. Cup end set screws can fit arc surfaces effectively prevent slipping ideal for shaft fixing. Dog point end achieves firm bite connection for strong anti loosening use. Nylon rubber tipped set screws avoid scratching workpiece surface play anti slip buffer and noise reduction role. Extended tip and ball plunger types support flexible ejection and precise positioning.

304 316 stainless steel set screws feature excellent rust resistance corrosion resistance suitable for outdoor humid marine electronic and high precision scenes. Carbon steel 40Cr 35CrMo alloy steel set screws pass black oxide treatment own high hardness high tensile strength fit heavy load high pressure industrial equipment. Brass set screws have good ductility anti oxidation performance for precision instruments and delicate electronic assemblies.

Comply with DIN913 DIN914 ISO international industry standards complete metric specifications M2 M3 M4 M5 M6 M8 M10 M12 to M20 and various inch sizes are available. Multiple strength grades including 4.8 8.8 10.9 12.9 can meet different load bearing usage demands.
