Description
The Hexagon Socket Set Screw (DIN 913) is a high-precision, headless fastener designed for applications where a flush surface and permanent positioning are critical. Manufactured from high-quality AISI 304 stainless steel, this set screw offers excellent corrosion resistance, strength, and durability, making it suitable for both indoor and outdoor applications.
Unlike standard screws, the DIN 913 variant features a flat end, providing a broad contact surface that applies even pressure against a shaft or mating part without marring or deforming the material. Whether used in pulley systems, gear assemblies, or precision instrumentation, this stainless steel screw ensures a secure, vibration-resistant lock that remains easy to adjust via its internal hex drive.
Features & Benefits
- Durable 304 Stainless Steel: Excellent resistance to corrosion, oxidation, and rust in humid or outdoor conditions.
- Flat End Design (DIN913): Provides stable and even pressure distribution without damaging mating surfaces.
- Hexagon Socket Drive: Enables precise torque control and a secure fit; prevents slipping during installation.
- High Strength and Wear Resistance: Maintains structural integrity under vibration, load, or repeated tightening.

FAQ:
Q1: When should I choose a Flat Point (DIN 913) over a Cup Point?
A: Choose a Hexagon Socket Set Screw with a flat point when you need to press against a thin-walled tube, a soft shaft, or a surface that requires frequent adjustments. If you need the screw to "bite" into the metal for a permanent, non-moving hold, a cup point might be better.
Q2: Is 304 stainless steel magnetic?
A: Typically, 304 stainless steel is non-magnetic or only slightly magnetic after the cold-working process. This makes these set screws ideal for electronic and medical applications where magnetic interference must be minimized.
Q3: Can these screws be reused?
A: Yes. Because the flat end does not damage the mating surface and the 304 stainless steel resists stripping, these screws can be tightened and loosened multiple times for maintenance or calibration.
Q4: What tools are needed for installation?
A: You simply need a standard metric hex key (Allen wrench) or a hex bit driver that matches the internal socket size of the screw.
Q5: Are these set screws suitable for high-vibration applications?
A: Yes. Their precise threading and strong material properties help maintain secure locking under vibration and repeated use.
