Socket Screw Range
Socket Head Cap Screws
Unbrako socket head cap screws run Property Class 12.9 at 1,300 N/mm² minimum tensile strength, 10,000 PSI above the industry standard, in metric M2 to M56 and inch BSW 1/8" to 1-1/2". The engineering sits where you can't see it: a Compound Fillet Radius that doubles fatigue life at the head-shank junction, and the 3R radiused root runout thread that lifts fatigue resistance 300% over conventional screws. Every batch carries E-Code lot marking for traceability back to raw material. Standard finish is black oxide to DIN 912 / ISO 4762; Geomet, PTFE, and hot-dip galvanized coatings come on request. Die makers, machine builders, and auto component plants across Noida-NCR buy these loose or boxed. Stocked at Sector 9, Noida; WhatsApp size and quantity for price.

Countersunk Socket Screws
Flush means flush: Unbrako countersunk socket cap screws seat their 90-degree heads level with the surface, so machine guards, guide rails, and sliding surfaces have nothing to snag. Property Class 012.9 gives 160,000 PSI (1,100 N/mm²) minimum tensile strength in alloy steel with black oxide finish, across M3 to M24 in full-thread (M3-M12) and partial-thread (M6-M24) versions, made to DIN 7991 / ISO 10642. The same Compound Fillet Radius and controlled thread runout as the flagship SHCS carry over, plus E-Code batch traceability. One design note: the countersunk head bears on less area than a cap screw head, so for heavy shear, add dowel pins or shoulder screws. Tool rooms and panel builders across Noida-NCR buy these regularly. Stocked at Sector 9, Noida; WhatsApp for price.
View Details & SpecsSocket Set Screws
Grub screw or set screw, same fastener, and Unbrako's version grips harder: the knurled cup point is hardened to HRc 45 minimum so it bites a permanent impression into the shaft, holding pulleys, gears, collars, and coupling hubs against rotation and axial creep. Headless full-body threads sit flush or below the surface, driven by an Allen key from the end face. Sizes run M3 to M20 in five point styles: knurled cup (DIN 916), flat (DIN 913) where you can't mark the shaft, cone (DIN 914) for permanent locking, plus dog and half-dog for positioning. High-carbon alloy steel, black oxide, heat treated for consistent clamping. Machine builders and packaging machinery plants across Noida-NCR order these by the box. Stocked at Sector 9, Noida; WhatsApp for price.
View Details & SpecsButton Head Socket Screws
Where a fastener stays visible, Unbrako button head socket screws do the job neatly: a low dome roughly 60% the height of a standard cap screw head, wide enough to spread bearing load, with a hexagon socket for proper torque. Class 10.9 alloy steel with black oxide covers M3 to M12 to ISO 7380-1, and the flange variant (ISO 7380-2) builds in a washer-like bearing surface for soft materials and oversized holes. The smooth contour has no sharp edges, which is why enclosure builders, furniture fitters, and medical equipment manufacturers pick them for panels people touch. For structural joints, step up to Class 12.9 cap screws; buttons are for light-to-medium duty where looks and low profile matter. Stocked at Sector 9, Noida; WhatsApp for price.

Hex Wrenches & Ballpoint Sets
A rounded socket usually means a cheap key, not a bad screw. Unbrako hex wrenches are chrome vanadium steel at HRc 52-58 with a hexagon profile made to match Unbrako socket dimensions exactly, so cam-out and socket wear stop being routine. Metric sizes run 1.5mm to 32mm, covering M2 through M56 screws; inch sizes go 1/16" to 3/4". The ballpoint versions engage up to 25 degrees off-axis for fasteners buried in pockets or behind obstructions, and the L-shape gives short-arm torque or long-arm speed. Buy individual keys or 9-piece holder sets, both to DIN 911. Maintenance crews and assembly lines across Noida-NCR keep spare sets at every station. Stocked at Sector 9, Noida; WhatsApp for price.
