Hollow Allen Bolts India | Industrial Fasteners Grade 8.8, 10.9, 12.9 High Tensile Supplier
Ananka Group is a reputable Hollow Allen Bolts Manufacturer that produces quality fasteners to use in light and high-strength industrial components. Hollow Allen-type bolts, which can also be called hollow-core socket head cap screws, are intended for small, torque demanding installations where weight savings and proximity are critical. Due to their ease of internal wrenching, strength, and appearance of high tensile, these bolts find a lot of application in robotics, aircraft, electronics, motor cars, and accurate instruments.
We provide hollow Allen bolts of titanium, alloy steel, stainless steel, and high-nickel alloys, and these products are strictly based on international standards, which include ASTM, DIN, ISO and BS. Our bolts are B2B designed to service all OEMs, EPC contractors, and international industrial procurement teams' needs. These fasteners can be made of any type of thread (metric/UNC/UNF), can be of any finish, and can be of custom dimensions, and thus are suitable where the engineering precision is highest. Our battery manufacturing facilities provide 100 percent material traceability, third-party inspection, and worldwide export that guarantees uniformity, on time delivery, and adherence to challenging project requirements.
