METRIC HEX BOLTS, PARTIALLY THREADED ( DIN 931): A hex machine bolt with metric thread pitch. Generally manufactured in accordance with DIN Standard 931 or ISO Standard 4014

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.

METRIC HEX BOLTS, PARTIALLY THREADED ( DIN 931): A hex machine bolt with metric thread pitch. Generally manufactured in accordance with DIN Standard 931 or ISO Standard 4014

An externally threaded fastener, with a trimmed hex head, but with no washer face on the bearing surface. (Its body tolerances are not as close as those of a hex cap screw.)

Used in a variety of general purpose applications (depending on the grade of the material) in situations where dimensional tolerances are not as critical.

An alloy or stainless steel hex bolt with a wider head than that of a standard hex machine bolt, manufactured in accordance with ASTM Standard A193.

Offers greater wrenching area than standard hex machine bolts. Used for pressure vessels, valves, flanges, and fittings for high-temperature service.

A low carbon steel hex bolt with a wider head than that of a standard hex machine bolt, manufactured in accordance with ASTM Standard A307.

Offers greater wrenching area than standard hex machine bolts. Used in heavy industrial work.

An alloy or stainless steel hex bolt with a wider head than that of a standard hex machine bolt, manufactured in accordance with ASTM Standard A320.

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.

An externally threaded fastener, with a trimmed, square shaped external wrenching head.

Used in applications where the use of power tools is impractical or undesirable. Offers greater bearing area for more positive gripping with a hand wrench.

A bolt having a forged head in the form of an open or closed anchor ring. Shoulder pattern eyebolts have an unthreaded shoulder below the anchor ring which is greater in diameter than the threaded shank.

Used in applications where a forged shank is required, e.g., in rigging when mounted atop a uniformly distributed weight.

A round head bolt with a square neck under the head and a unified thread pitch.

Designed to keep the bolt from turning when a nut is being tightened. The short neck variety is used in sheet metal where a standard sized neck would create an obstruction.

Elliptical Head Cement Mill Liner Bolt (ISO 898-1): Aelliptical head cement mill bolt threaded to the head with metric thread pitch. Generally manufactured in accordance with ISO 898-1.

Especially hot forged head form uniform grain flow with unbroken flow line make head stronger prevent failure & add strength. Fully CNC machined form over size material ensures no de-carburizing or surface crack. Rolled threaded bolts are smoother surface and close tolerance; fully formed / uniform threads provide extra shear strength & resist stripping. 100% satisfy thread Go & No-Go gauge test.

Elliptical Head Cement Mill liner bolts are heat treated in controlled atmosphere eliminating possibilities of decarburization or surface carburization to ensure maximum strength and toughness.

Liner bolt is a hot forged head from uniform grain flow with an unbroken flow line to make the head stronger, prevent failure & add strength. It is Fully CNC machined form oversize material ensures no de-cementation or surface cracking. Rolled threaded bolts are smoother surface and close tolerance; fully formed / uniform threads provide extra shear strength & resist stripping.

Liner bolt are heat treated in a controlled atmosphere eliminating possibilities of de-cementation or surface carburisation to ensure maximum strength and toughness.
