Grade C lock nuts equal 75% of the bolt proof loads specified for SAE J-429 Grade 8, and ASTM A-354 Grade BD bolts. IFI-100 does not govern lock nuts above 1". The values shown in the chart are to be used as a mid-range guideline. ** Torque values for 1/4" and 5/16" sizes are in inch lb. All other torque values are in foot lb. Grade C Grade B Grades of stainless steel A2, A4 in relation to fasteners Stainless steel, when used for fasteners (nuts, bolts, screws etc) have British standards. BSENISO 3506 replaces BS6105. Part 1 covers bolts, screw and studs, part 2 nuts and part 4 tapping screws. To all intents and purposes, when we see type A2 stainless steel, we can also call it Type 304. Likewise A4 grade can be called type 316 but more: Grades of stainless steel fasteners on the market.Jul 01, 2020 · Quality Stainless Steel Fasteners Manufactured by Marsh Fasteners.

Hex Bolt Identification, Markings and Strength Chart. Additonal information on bolts is located at the bottom of the webpage. Note:Some bolts share identical head identification and have significantly different strengths. Informational Video:Stainless Steel Bolt Strength and GradesStainless commonly comes in grades 18.8 (304) or T316. Stainless steel bolts are rated for corrosion resistance. Bolt strength is rated in PSI (pounds per square inch). A stainless steel bolt has the same PSI rating as a grade 5 bolt (125,000 PSI). A grade 8 bolt has a stronger rating with a PSI of 150,000. Video 10:Stainless Steel Bolt Grades Stainless Steel Grades -Nuts, Bolts, Screws, Washers, StudsSimilar to steel, it is a relatively poor electrical conductor. When piping is flanged together with stainless bolting, it is often done by using ASTM A193 B8 Studs with A194 Grade 8 nuts, OR A194 B8M stud bolts & A194 grade 8M nuts respectively. Stainless steel is grouped by its crystalline structure.
ASTM A307 grade C has been replaced by ASTM F1554 grade 36. Grade 2 requirements for diameters ranging from 1/4" through 3/4" only apply to headed fasteners up to and including 6" in length, and to studs of all lengths. For headed fasteners longer than 6", see SAE J429 grade 1.

Marks BoltsMay 26, 2016 · Stainless Hex Bolts .. there are different grades of stainless but the most common are bolts made in the 303 and 304 series of stainless. Many people think stainless bolts are very hard. This is not true. 300 series stainless is just a tad under a Grade 5 in strength. Usually a tensile strength in the range of 112,000 to 116,000 PSI.
