Both of these patterns will be standard as a heavy hex nut, meaning that it will require a larger wrench than a standard “finished” pattern nut. Most importantly, we have case hardened / strain hardened nuts too!

Standard Specification for Carbon and Alloy Steel Nuts for Bolts for High Pressure or High Temperature Service, or both. ASTM A194 specification covers a variety of carbon, alloy, and martensitic stainless steel nuts in the size range 1/4 through 4 in. …

Choose from our selection of grade 8M nuts, including hex nuts, locknuts, and more. Same and Next Day Delivery.

ASTM A194 Grade 8M nuts are high-quality fasteners made from austenitic stainless steel, designed to offer excellent resistance to corrosion, durability, and strength in high-pressure and high-temperature environments.

Hexagon full nut to ASME B18.2.2 and B18.6.3. Typically fitted with a spanner or ratchet with socket. The most popular nut type, and used for decades on all types of assembly throughout the world.

Accurately developed and designed, these ASTM A194 GR.8M Stainless Steel Coupler Nuts are required for their reliable performance and tough construction. These ASTM A194 GR.8M Stainless Steel Nylon Insert Nuts are generally used in Food processing machinery, mainly in beer brewing, winemaking, and milk processing.

A194 Gr8M U-nuts provide better clamping force and prevent any axial movement in the system. These nuts create sufficient friction amongst threads to prevent unscrewing. The A194 Gr 8Ma Wing Nuts have good mechanical properties and can be heat treated.

Lightning Bolt has one of North America’s largest inventories of A194 Grade 8M Nuts. This pattern is commonly found as a heavy hex nut. The A194 Grade 8M nut is essentially very similar, however the standards call for these to made from an 316 type of stainless steel.

8M螺母材料化学性能：316含Mo元素，其耐蚀性高于304，在高温下耐蚀性更好，对亚硫酸、硫酸、磷酸、醋酸、甲醛、氯盐、卤素、亚硫酸盐等有良好的耐蚀性。 在高温条件下，当硫酸浓度低于15%和高于85%时，316有广泛的用途，316还具有良好的耐氯化物腐蚀的性能，通常用于海洋环境。 316有晶间腐蚀倾向，在450~850°C的敏化温度范围区间尽量不要连续使用，进行过固溶处理的316不锈钢抗晶间腐蚀性能较好。 316在低浓度F离子/Cl离子醋酸介质中能钝化，致密钝化膜 …
