Vimal Industrial Corporation is a leading stockist and supplier of DIN 916 socket set screws based in Mumbai, India. Manufactured according to DIN 916 standards, these fasteners feature an internal hex (Allen) drive with a cup-point tip, designed to deliver strong, vibration-resistant holding power in shafts, collars, pulleys, couplings, and mechanical locking applications. DIN 916 screws are engineered for precision clamping where a headless, flush-fitting fastener is essential.
With a comprehensive inventory covering multiple diameters, lengths, property classes, and corrosion-resistant materials, we support OEMs, machine builders, automation companies, MRO teams, and engineering contractors requiring reliable, high-strength set screws for critical holding and alignment tasks.
DIN 916 cup-point screws are one of the most widely used set-screw types for secure locking, high surface penetration, and strong resistance to loosening under motion. Vimal Industrial Corporation maintains ready stock from M3 up to M24, with standard high-tensile grades such as 45H, 12.9, and stainless-steel options for corrosive environments.
All screws comply with DIN dimensional tolerances, ensuring correct socket depth, point geometry, thread tolerance, and hardness. Products are stored in climate-controlled warehouses, backed with mill test certificates, chemical and mechanical property reports, lot-traceability, and optional third-party inspection. With our Mumbai warehouse and nationwide logistics capability, we ensure quick dispatch for both urgent breakdown maintenance and scheduled project needs.

A DIN 916 screw is a headless set screw with an internal hex drive and a cup-point tip, used to lock components onto shafts or secure mechanical parts where no external head should protrude.
The cup-point provides a sharp, concave seating surface that bites into the mating material, offering excellent holding power, vibration resistance, and torque transfer, making DIN 916 ideal for rotating or high-motion assemblies.
Common materials include alloy steel (grade 45H or class 12.9) for high strength, and stainless steel A2/A4 for corrosion-resistant applications. Black-oxide and zinc-plated finishes are also widely used.
They are widely used in motors, couplings, gear assemblies, collars, pulleys, automation mechanisms, and precision machinery, wherever accurate positioning and reliable locking are required.
As a dedicated authorized APL dealer, we supply DIN-certified, fully traceable set screws, maintain large ready stock, and provide fast pan-India delivery along with technical support for selecting the correct screw type and grade.
