Vimal Industrial Corporation is a leading stockist and supplier of DIN 915 socket set screws based in Mumbai, India. Built according to DIN 915 standards, these screws feature an internal hex (Allen) drive with a dog-point tip, designed to provide precise axial positioning without damaging the mating surface. The extended cylindrical point ensures accurate engagement with a pre-drilled hole or slot, making DIN 915 screws ideal for applications where repeatable alignment, guided locking, or controlled linear positioning is required.
We maintain a comprehensive inventory of DIN 915 dog-point set screws in multiple diameters, lengths, and material grades—supporting OEMs, automation companies, machine builders, instrumentation manufacturers, and MRO teams that rely on precise, non-destructive fastening.
DIN 915 dog-point screws are widely used where components need to be positioned with accuracy, frequently adjusted, or guided along a predetermined slot. Vimal Industrial Corporation maintains ready stock from M3 to M24, available in hardened alloy steel (45H, 12.9) and stainless-steel grades A2/A4 for corrosive or hygiene-sensitive environments.
All products comply with DIN 915 dimensional and mechanical requirements, including point length, diameter tolerances, hardness, and socket depth. Our controlled warehouse ensures batch consistency, and every order can be supplied with mill test certificates, chemical/mechanical test reports, and lot traceability. With our Mumbai warehouse and strong pan-India logistics, we support urgent industrial maintenance and routine OEM production schedules alike.

Stop thinking of it as just a screw. The DIN 915 is an alignment tool. That cylindrical “Dog Point” at the tip is designed to lock into a pre-machined hole. Unlike a standard cup point that just digs into the surface, this screw nut bolt variant creates a permanent mechanical stop. It’s the ultimate bolt fastener for shafts that shouldn’t budge an inch.
Actually, yes. Clever engineers use the unthreaded tip of a DIN 915 as a tiny axle for levers or small rotating parts. The hex drive keeps the screw nut bolt fixed in the housing, while the smooth tip allows the mating part to swing freely. It’s a 2-in-1 Industrial Hardware hack that saves space and parts.
If the dog point is too long, it bottoms out in the hole before the threads tighten. If it’s too short, it won’t engage the groove. This is why you need a precise Fasteners Supplier India who understands “Full Dog” vs. “Half Dog” specs. A mismatched bolt fastener here can cause a high-speed pulley to fly right off the motor.
If you need 100% traceability and “Ready-to-Ship” inventory, Vimal Industrial is the name to trust. Being a leading Nut Bolt Supplier Mumbai, we don’t just sell parts; we provide the technical data you need to ensure your screw nut bolt assembly is safe, durable, and up to international DIN standards.
Because these are “Set Screws,” they need to be harder than the material they are locking into. Standard DIN 915 screws from a reliable Fasteners Supplier India are heat-treated to 45H hardness. This ensures the tip of the bolt fastener doesn’t deform under the heavy pressure of a rotating shaft.
