Features of Stainless Steel DIN 913 Grub Screws
Set Screw Flat Head Title:
ISO 4026、DIN 913/914/915 stainless steel 304 316 flat point set screw m3-m12 cone oval dog point
Grub Set Screw Cup Point Specifications:
Its core function is to achieve positioning, anti loosening, and fixation of two parts (such as shaft and hub, gear wheel, and belt wheel) by tightening and pressing the surface of the connected part, generating friction and compression force. It does not require nut fitting and can fully sink into the surface of the workpiece, adapting to compact space and flat appearance requirements.
Standard set screws are headless fully threaded screws that comply with international/national standards such as ISO 4026, DIN 913/914/915, GB/T 71/73/75/79, etc. They are tightened using internal drive structures such as hexagonal, slotted, and Phillips grooves to achieve relative fixation between parts through end pressure, preventing axial movement and circumferential rotation.
Material:
Carbon steel (medium carbon steel/low carbon steel), stainless steel (304/316): corrosion-resistant and rust resistant, with 316 having stronger corrosion resistance;Alloy steel (40Cr, 42CrMo), brass/copper alloy, nylon/plastic, etc.
Surface Treatment:Blackening/oxidation: Zinc plating (blue white zinc/color zinc), nickel plating, phosphating, passivation,etc
Drive Style: Hex Socket,Slotted,Torx,Square Socket,etc
Size:
Metric: M2, M2.5, M3, M4, M5, M6, M8, M10, M12, M16, etc. Thread accuracy is commonly 6H.

Feature:
Headless Design: No protruding head, can fully sink into the threaded hole of the workpiece, flat/concave surface, no interference, no risk of scratching.
Full threaded structure: The entire shaft has effective threads, including the end (Point), and is suitable for installation at different depths.
Internal drive mode: Only the top is equipped with a drive slot (hexagonal socket is the most commonly used), and special tools (hexagonal wrench, screwdriver) are required for installation.
End differentiation: The end (Point) has various shapes (Ball tip, Extended tip, oval, flat, cone, etc.), suitable for different fixed and positioning scenarios.
Standardization: Threads, dimensions, materials, and performance all follow unified standards, with strong interchangeability.
