When components need to stay locked in place without shifting, DIN 916 Socket Set Screws are preferred for their strong holding capability. The cup-point design creates a firm bite into the surface, helping maintain position even under continuous movement or vibration.
At Vimal Industrial Corporation, we supply DIN 916 screws that fit seamlessly into mechanical assemblies like shafts, collars, and couplings, where space is tight and performance cannot be compromised. These screws are often chosen in setups where once fixed, the component should not move or slip during operation.
We keep multiple sizes, lengths, and material options ready to match different industrial requirements. As a reliable screw supplier in Mumbai and experienced fastener suppliers, we ensure smooth availability for both production and maintenance needs. Our range also includes stainless steel fasteners for applications requiring corrosion resistance and durability. Built for grip and consistency, DIN 916 screws help maintain alignment and stability in real working conditions without adding complexity to the assembly.
When a joint needs to stay locked without shifting, the holding strength of the screw itself becomes critical. DIN 916 Socket Set Screws are built for this purpose, the cup-point tip creates a firm seating against the surface, helping resist loosening in assemblies exposed to motion or load changes.
At Vimal Industrial Corporation, we keep DIN 916 screws readily available from M3 to M24 in high-tensile grades like 45H and 12.9, along with stainless steel options for corrosion-prone environments. These screws are commonly used in compact mechanical setups where space is limited but a strong internal grip is required.
Each batch is supplied in line with DIN standards, covering thread accuracy, point geometry, and hardness. As a consistent screw supplier in Mumbai and experienced fastener suppliers, we ensure material is ready for both urgent maintenance and planned production. Our range also includes stainless steel fasteners for applications requiring long-term durability. With organized stock, proper documentation, and a strong delivery network, we help industries source fastening components without delays or uncertainty.
DIN 916 Socket Set Screws are chosen when a component needs to be locked in place from within, without any external projection, and still handle movement or load without slipping. The cup-point helps create a firm internal hold, making them suitable for compact and performance-focused assemblies.
Shaft & Rotating Parts – Fixing gears, pulleys, and collars so they stay aligned during operation.
Machine & Automation Setups – Holding cams, levers, and moving linkages at set positions.
Drive & Motor Assemblies – Securing couplings and rotating elements where movement is continuous.
Precision Equipment – Used for fine adjustments in instruments and controlled mechanisms.
Tooling & Adjustable Setups – Locking stops, pins, and movable parts that require repositioning.
Maintenance & Retrofit Work – Useful in tight spaces where standard fastening isn’t practical.
These screws are mainly used when the goal is internal locking with strong grip, without affecting the outer design or space of the assembly.
Getting the right DIN 916 Socket Set Screws isn’t just about specs, it’s about consistency in how they perform once installed. At Vimal Industrial Corporation, the focus is on supplying fastening solutions that hold firmly in real working conditions, not just on paper.

The DIN 916 is built with a unique hollowed-out “cup” at the tip. When you torque this screw nut bolt down, the thin edges of the cup dig a circular trench into the shaft. This provides a double-action grip that resists both radial and axial movement. If you need a bolt fastener that won’t budge under high-speed rotation, this is the industry standard.
It’s the most versatile set screw ever made. Unlike the sharp cone point (DIN 914) that can crack a shaft, the cup point of the DIN 916 provides a high-friction lock with less risk of material fatigue. Every Nut Bolt Supplier stocks these in the highest volume because they fit 90% of all pulley and gear applications.
Technically yes, but there’s a catch. The sharp edge of the cup flattens slightly after the first high-torque installation. If you reuse it, the “Bite” won’t be as deep. For safety-critical fasteners screw bolts in heavy machinery, we always recommend a fresh screw nut bolt to ensure a 100% secure grip every time.
The DIN 916 is designed to disappear. By sitting flush inside the hole, it allows rotating collars and shafts to spin without a protruding bolt fastener head causing a safety hazard or unbalancing the machine. It’s the “Secret Agent” of the Industrial Hardware world, doing its job while staying invisible.
If you need 100% traceability and immediate delivery, Vimal Industrial is the premier Nut Bolt Supplier Mumbai. We don’t just move boxes; we provide the Material Test Reports (MTR) and technical backing to ensure your fasteners screws bolts assembly is safe and up to international DIN standards.
