A194 = Standard specification for nuts in many different material types.

ASTM A453

ASTM A453 Grade 660 is a material specification for studs, bolts, nuts and other fasteners, intended for use in high temperature bolting applications.

ASTM A453 Grade 660 is classified into 4 property class namely A, B, C & D, each designated with different tensile and stress rupture properties. Grade 660 fasteners are used in bolting boilers, pressure vessels, pipeline flanges and valves, intended for high temperature service. ASTM A453 grade 660 material is chemically equivalent to ASTM B638 grade 660 stainless steel alloy, also known by alloy A286 and UNS S66286, heat treated to achieve properties defined in ASTM A453 specification.

Hex bolts

A flange hex bolt is a bolt that has a washer-like flange cast into the hexagonal head of the bolt. Designed to be used without the aid of a flat or locking-style washer, the flange hex bolt is manufactured to properly displace the torque and clamping force of the bolt over a wider area than that of a typical hex head bolt.

Mechanical Properties:

Many metals are used in the manufacture of a flange hex bolt, from common mild steel to stainless steel and titanium, and each type of bolt has a specific use.

Metric Grades : 4.6, 8.8, 10.9, 12.9
Inch Grades : 2, 5, 8

Standard sizes of hex bolts

Used a great deal in the automobile industry, this type of bolt allows assembly line workers to install the fasteners much faster than a comparable bolt and washer.

For most applications on the automobile, mild steel is the metal of choice for the flanged bolt. This type of bolt allows for sufficient torque and will endure several tightening cycles that might otherwise fatigue other types of fasteners. Stainless steel fasteners are most commonly used in food-quality machinery and pipelines, as well as caustic areas that might serve to corrode a mild steel fastener in a minimum amount of time.

Hexagon socket bolts

The hexagon socket head bolt is a cap screw with a hexagon head, designed to be driven by a wrench (wrench). Cap screws that comply with ASME B18.6.3 have stricter tolerances on head height and shank length than hexagonal bolts.

Eye Bolts

The eye bolt (otherwise known as a lifting eye bolt or eyelet) is a type of bolt with a loop at one end. They are used for a wide variety of material lifting applications and may either pivot or swivel. The securing eye must be securely attached to the structure before ropes or cables are tied for lifting.

The design of a carriage bolt includes a large round, domed head with an externally threaded bolt projecting from it. The head is typically at least twice the diameter of the bolt shaft, and usually does not have slots for a screwdriver or other driving device. Underneath the head, there is a square fitting that grips the wood as the bolt is placed and fastened, keeping it from twisting or turning and otherwise maintaining a snug fit.
