Description
Allen bolt manufacturers in India
Get premium quality hexagon socket head cap screws from Kant Fasteners – a top name among Allen bolt manufacturers in India.
Precisely controlled socket depth gives optimum wrench engagement, allows full tightening without reaming the socket or cracking, with ample metal in crucial fillet area. Especially hot forged head forms uniform grain flow with unbroken flow line make head stronger prevent failure & add strength.
CNC machined from oversize material ensures no de-carburizing or surface crack., Rolled threaded screws have a smoother surface and close tolerance, fully formed threads provide extra shear strength & resist stripping.
KANT SHCS are heat-treated in a controlled atmosphere eliminating possibilities of decarburization or surface carburization to ensure maximum strength and toughness. Socket IS0 4762, ISO 1364, DIN 912, ASNI B18.3.1M.

Kant Fasteners manufacture and supply high-quality industrial hex head cap screws.
We are one of India’s leading Industrial hexagon socket head screw manufacturers.
Socket head cap screws use
The screws are types of fasteners, in some ways similar to a bolt, typically formed from metal, and described by a helical ridge, or an external thread. Socket Head Cap Screws are utilized to secure elements by drilling in and wedging them into the material. At the same time, the thread makes grooves in the attached material that helps pull attached parts together and stop pull-out. There are several Socket Head Cap Screws for diverse types of raw materials; those usually fastened by screw hexagon head cap are materials like wood, sheet metal, and plastic.
The industries that commonly utilize our range of cap screws include:
- Energy Sector
- Chemical Industry
- Aerospace Industry
- Defence Industry
Socket Head Cap Screws Finishes
Screws are fasteners, usually driven by screwdrivers to fix and unfix components; they are often made of metal. They also contain a hollow in their hexagon screw heads to ensure the screwdriver ends can fit in, and turn them. Their lengths are threaded to enable them to fit into wooden materials, walls, and metals.
- Zinc and Chromate Finish: Silvery appearance that provides corrosion-resistance for Socket Head Cap Screws.
- Plain Finish: Socket Head Cap Screws without any coating.
- Zinc Plated: Socket Head Cap Screws covered with zinc.
- Zinc and Yellow Chromate: Offers better resistant to corrosion to Socket Head Cap Screws than Chromate.
- Hot Dipped Galvanized(HDG) Socket Head Cap Screws: Gives superior resistance to decay due to being dipped in molten zinc.
Hex Bolt Dimensions
As hex bolt cap screw suppliers, we have many people that ask us if the names of hex cap screws and hex bolts are interchangeable, and they are not.A hex bolt is less precise, and as a result, it is cheaper than a hexagon socket head cap screw. Added features of hex cap screws that make them better is that they are made with a higher degree of preclusion (i.e. tighter tolerance) and also maintain a washer facing below the head of the bolt.
Hex bolts are used to secure two or more components together to assemble them together. A bolt has a head and external threads that together form a mechanical device designed for fastening.
The size and length of hex bolt fasteners are specified in inches, commonly fractional instead of decimal. Their sizes refer to the trivial diameter of the bolt head, while the length is simply to show long a bolt is. Hex bolts generally range from 1/4″ to 4″ in diameter, and 1/4″ to 1 1/2″ sizes are customarily available.
The fasteners are manufactured to universal specifications known across industries globally. If you are looking for a grade 8 hex cap screw or a grade 5 hex cap screw, these dimensional measurements will be the same. Only the raw material that they are made from will be different.
Drawing and Dimensions
KANT hexagon socket head cap screw is one of the strongest threaded fasteners with higher pressures, higher stresses and higher speeds demand stronger, more reliable joints and stronger, more reliable fasteners to hold them together. They have the extra strength and fatigue resistance required for total reliability in high strength fastening. This International Standard specifies the characteristics of hexagon socket head cap screws with coarse pitch thread from M16 up to and including M64 and product grade A.
The Socket is deep enough for full tightening without cracking, but not deep enough to weaken the head area and cause failure. A scientifically designed radius at the root is responsible for adding both fatigue resistance and strength in the screw most prone to failure. Fillet at the junction of head and shank gives more then double fatigue life in the head area without reduction of critical bearing area. Heads are correctly proportioned to screw size, assuring full clamping force without indentation and loss of preload.
Physical properties of higher stress levels are a direct result of customised heat treatment. Material selection in steel from lot to lot require that each “heat” of KANT socket head cap screws be heat treated in accordance with its specific chemistry. Every lot of steel is pre-tested, and its treatment personalized to produce a uniform product.
The head of hexagon socket head cap screw is forged because it forms metal produce uniform grain flow which makes heads stronger by compressing the metal. The Head area is strictly perpendicular to the screw body to avoid strains and misalignment.
