AUSTENITE FASTENERS PVT. LTD

Makarpura, Vadodara, Gujarat

A headless screw threaded the entire length, with a hexagonal drive at one end and a point at the other end (e.g., cup, half dog, oval, flat, and cone).

Used for internal wrenching and where frequent disassembly or adjustment occurs.

METRIC HEX BOLTS, FULLY THREADED (DIN 933): A hex machine bolt threaded to the head with metric thread pitch. Generally manufactured in accordance with DIN Standard 933 or ISO Standard 4017

Hex bolts (six sided heads) are the industry standard for fasteners with forged heads. ASTM A307 grade A bolts, all SAE hex bolts, and several other common specifications require a standard (finished) hex head. For specifications such as A307 grade B, A325 and A490 that require a heavy hex pattern, refer to dimensional tolerances for heavy hex bolts or structural bolts.

• GRADE: SS 304
• GRADE SS 316
• HIGH TENSILE Gr. 8.8 / Gr. 10.9
• MILD STEEL Gr. 4.6 / Gr. 5.6

An externally threaded fastener with metric threads, a cylindrical head with a flat chamfered top surface, knurled cylindrical sides, and a hexagonal recess. Generally manufactured in accordance with DIN Standard 912 or ISO Standard 4762

Ideal for precision assembly work with close tolerances and applications needing a well tooled appearance. Supplies greater tensile strength than equivalent sizes of hex cap screws while requiring less surface area or counter-bore since the fastener is internally wrenched.

Has a similar thread design as a metric socket head cap screw. However, the dome-shaped head is wider and has a lower profile than a metric socket head cap screw. Generally manufactured in accordance with ISO Standard 7380.

Used when a wider bearing surface or a smoother, more finished appearance is desired. Button head cap screws do not afford the strength of socket head cap screws and are designed for light fastening applications. They are not recommended for critical, high-strength applications.
