ASTM A193 Grade B16 Hex Cap Screws. Boltport fasteners manufactures ASTM A193 Grade B16 hex cap screws to ASME B18.2.1, B18.104.22.168M, DIN 933, ISO 4017 and UNI 5739 standards, with coarse, fine and extra fine threads. We produce both metric and imperial sized hex cap screws to ASTM A193 Grade B16 specification. ASTM A193 Grade B16 Specification - Boltport FastenersASTM A193 Grade B16 specification defines requirements for chemical composition, mechanical properties such as tensile, yield strength, hardness, heat treatment, product marking, etc., for bolts, studs, screws, threaded rods and other external threaded fasteners intended for high tensile bolting application in high temperature, high-pressure service or both.
Boltport uses Alloy Steel AISI 4140 bar stock or forging stock to produce B7 headed and non-headed bolts. A193 Grade B7 is the most commonly used Bolt specification coupled with A194 Grade 2H Nuts for Bolting Carbon Steel pipeline. A193 B7 bolting is available in metric sizes from M6 to M180 and imperial sizes from 1/4 to 7 inches, in diameter. ASTM A193 Grade B8 - Boltport FastenersA193 grade b8 is chemically equivalent to (AISI 304) 18-8 stainless steel alloy with tensile strength diversified in two different tensile classes namely class 1 and class 2. A193 Grade B8 class 1 bolts are carbide solution treated with maximum tensile strength requirement of 75 ksi or 515 MPa, yield 30 ksi or 205 MPa, and maximum hardness of 223 HBW whereas grade b8 class 2 bolts are carbide solution ASTM A193 Grade B8 Bolts, Stud Bolts, Fasteners - BoltportASTM A193 Grade B8 Chemical Composition.

ASTM A193 Grade B8M - Boltport FastenersASTM A193 Grade B8M ASTM A193 Grade B8M is a standard material specification for high tensile 316/316L stainless steel bolts, screws, studs or other external threaded fasteners for high-temperature, high-pressure service and other special purpose applications. ASTM A193 Grade B8M Class 2 - Boltport FastenersASTM A193 Grade B8M Class 2 ASTM A193 Grade B8M Class 2 is a carbide solution treated and strain hardened 316/316L stainless steel bolting material specification, with higher tensile strength requirement of 125 ksi or 860 MPa and 100 ksi or 690 MPa and maximum hardness of 321 HBW or 35HRC.
ASTM A320 Grade L7 is a standard specification for high tensile 4140 alloy steel bolting materials, intended for use in low temperature services. The term "bolting material" as used in this specification covers, rolled, forged or strain hardened bars, bolts, screws, studs and stud bolts. These alloy steel fasteners are used for bolting pressure ASTM SA193 B8 Stud Bolts, ASTM A193 B8 Class 1 Hex Bolts Our ASTM A193 Grade B8 Bolt is a good select for sea water submissions, which as well has remarkable exhaustion resistance. These ASTM A193 Grade B8 Stud Bolts also has outstanding resistance to a range of corrosive media, being particularly resilient to crevice and pitting corrosion. Chromium-Molybdenum Alloy Steel - ASTM A193 Grade ASTM A193 Grade B7 is a material specification for low alloy chromium-molybdenum steel, used for manufacturing of bolts, studs, stud bolts and other fasteners for bolting pressure vessels, valves, flanges and fittings for various process industries across major industrial sectors.
