Socket Screw Range
Socket Head Cap Screws
Unbrako Socket Head Cap Screws (SHCS) are the flagship fastener of the world's leading socket screw brand, trusted across 35 countries since 1911. Made from premium alloy steel with black oxide finish, these Property Class 12.9 cap screws deliver 1,300 N/mm² minimum ultimate tensile strength — 10,000 PSI stronger than the industry standard. Available in metric sizes M2 through M56 and inch sizes BSW 1/8" through 1-1/2", Unbrako SHCS feature the patented Compound Fillet Radius that doubles fatigue life, and the 3R Radiused Root Runout Thread that increases fatigue resistance by 300% over conventional screws. Every screw carries the patented E-Code lot marking for full batch traceability from raw material to finished product. Shri Narayan Machinery LLP stocks the complete Unbrako SHCS range in Noida for automotive, aerospace, heavy machinery, and general engineering work across Delhi NCR.

Countersunk Socket Screws
Unbrako Countersunk Socket Cap Screws (CSK) provide a flush-mounted fastening solution where a smooth, snag-free surface is essential. Available in metric sizes M3 through M24 with Property Class 012.9, these screws deliver 160,000 PSI minimum tensile strength while sitting completely flush with the work surface. The 90-degree countersunk head seats into a matching countersink with no protrusion — critical for machine guards, cover plates, sliding surfaces, and aerodynamic assemblies. Made from alloy steel with Unbrako's proprietary heat treatment, each screw benefits from the same Compound Fillet Radius, controlled thread runout, and E-Code traceability that define the Unbrako quality standard. The hexagon socket drive permits high-torque application in recessed or confined spaces where hex head bolts cannot reach. Shri Narayan Machinery LLP supplies the full Unbrako CSK range in Noida for precision engineering and manufacturing.
View Details & SpecsSocket Set Screws
Unbrako Socket Set Screws, also known as grub screws, are headless fasteners that secure components against or within a shaft using point pressure alone. Available in metric sizes M3 through M20, these set screws feature the Unbrako knurled cup point that bites into the mating surface at a minimum hardness of HRc 45, creating a permanent impression for strong holding power against rotation and axial movement. The full-body hexagon socket allows flush or below-surface installation — useful for shaft collars, pulleys, gears, and couplings where no external protrusion is permitted. Made from high-carbon alloy steel with controlled heat treatment, Unbrako set screws deliver consistent clamping force across millions of fastening cycles. Five point styles are available (knurled cup, flat, cone, dog, half-dog) so engineers can pick the right point geometry for the application. Shri Narayan Machinery LLP supplies Unbrako set screws in Noida with full technical guidance.
View Details & SpecsButton Head Socket Screws
Unbrako Button Head Socket Screws offer a low-profile, refined fastening solution where a smooth dome-shaped head is preferred over the cylindrical head of standard cap screws. Available in metric sizes M3 through M12, these fasteners feature a wide, shallow dome head with a hexagon socket drive that gives a clean finished appearance while maintaining strong clamping force. The button head design distributes bearing pressure over a wider area than a countersunk screw and protrudes less than a standard socket head cap screw — a good compromise between strength and aesthetics. Made from alloy steel with black oxide finish, Unbrako button heads use the same premium metallurgy and heat treatment that define all Unbrako products. Also available in flange button head configuration for increased bearing surface without a separate washer. Shri Narayan Machinery LLP in Noida supplies the complete Unbrako button head range for consumer equipment, enclosures, and light-duty engineering.

Hex Wrenches & Ballpoint Sets
Unbrako Hexagon Wrench Sets are precision-manufactured L-shaped Allen keys built to give the exact fit and torque transfer that Unbrako socket screws demand. Available in metric sizes from 1.5mm to 32mm and inch sizes from 1/16" to 3/4", these wrenches are made from chrome vanadium steel with a black finish for corrosion resistance and sure grip. The precise hexagon profile matches Unbrako socket dimensions exactly, minimizing cam-out and socket wear even under repeated high-torque use. For applications needing angled access, Unbrako Ballpoint Hexagon Wrench Sets feature a radiused ball end that allows engagement at angles up to 25 degrees off-axis — essential for reaching fasteners in confined spaces, recessed pockets, or obstructed locations. Both standard L-shape and ballpoint sets are available individually or in holder sets for workshop organization. Shri Narayan Machinery LLP in Noida supplies the complete Unbrako wrench range as individual keys and complete sets for maintenance and assembly.
