INTERNAL SERRATED WASHERS

Quick Overview

Internal tooth lock washers have teeth along the inside diameter. They prevent nut and bolt heads from loosening. Serrated lock washers have serrations along the outside diameter that prevent loosening and increase the washers locking power. Stainless steel is a strong, corrosion-resistant alloy with excellent resistance to heat. It is used in high-stress, outdoor and corrosive applications. Bulk material handling equipments  can provide Cold Forged & Hot Forged Internal Serrated Washer / Special Internal Serrated Washer with complete material compliance as both Metric & Imperial Inch sizes. Types of coating for internal serrated washer / special internal serrated washer that can be offered are electro zinc plating, hot dip galvanizing, ptfe fluorocarbon coating, aluminizing, ceramic filled fluorocarbon coating, nickel plating, zinc coating, electro zinc cobalt plating, electro zinc nickel plating, phosphate coating, electro less nickel plating, electro cadmium plating, dacromert 320 / 500 coating, pickled passivated, silver plating, chrome plating, etc. Internal Serrated Washer / Special Internal Serrated Washer can be avail in various grade materials as mention below: Carbon Steel:Grade 8.8, 10.9, 12 Alloy Steel: ASTM A182 F1, F5, F9, F11, F12, F22, F91, F92, AISI 4130, 4140, 4340, EN19, EN24, ASTM A193 B7, ASTM A193, A194, A593, A594, A563, A490, A453, A449, A325, A320, A307, B564, F568, F436, F1554, EN 3506-1, ASTM B16, B5 Stainless Steel (SS): 409, 410, 420, 430, 416, 304, 304l, 316l, 316, 310, 347, 347H, 321, 321H, 317, 317L, 316LN, 446C, AISI 660, 254SMO, Alloy 254 Precipitation Hardening Steel (PH): 15-5PH, 17-4PH, 17-7PH, 13-8 MO Duplex Steel (DSS): 2205, F51, UNS S31803, S32205 Super Duplex Steel (SDSS):2507, F53, UNS S32750, Zeron 100, F55, UNS S32760 Inconel: Alloy 600, 601, 617, 625, 690, 702, 706, 713C, 718, 722, 725, 738, X750, 751, 901, 903, 925, 945 Incoloy:Alloy 800, 800H, 800HT, 825, 27-7Mo, UNS S31277 Monel: Alloy 400, 500 Hastelloy: Alloy C22, C276, X Copper(Cupro) Nickel: CU-NI 90/10, CU-NI 70/30 Nitronic: Super Alloy 32, 33, 40, 50, 60, UNS S20400, UNS S24100, UNS S24000, UNS S21900, UNS S20910, XM-19, UNS S21800, Alloy 218 Nimonic: Alloy 75, 80A, 90 High Speed Tool Steel (HSS): M2, M42, Tungsten Carbide Maraging (Vascomax) Steel: C200, C250, C300, C350 Invar: Super Alloy 36, 42, 46, 48, 52, 59, NILO 36, 42, 46, 48, 50, Nicrofer 5923, Pernifer 36, 40, 46, 48, 50 Kovar: Alloy F15, NILO K, Pernifer 2918 Other Super Nickel Alloys: Alloy A286, ASTM A286 GRADE 660A, ASTM A286 GRADE 660B, ASTM A286 GRADE 660C, ASTM A286 GRADE 660D, UNS S66286, WS 1.4980, Waspaloy, AL6XN, UNS S08367, Custom 450, UNS S45000, Sanicro 28, Alloy 20, Alloy 330, Titanium: Alloy Grade 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12 Aluminum: Alloy 7075, 6061, 2024 High Temperature Alloys: 25CrMo4, DUREHETE 1055, DUREHETE 900 T22, 21CrMoV5.7, DUREHETE 950 T31 Various applications of Internal Serrated Washer / Special Internal Serrated Washer are boiler & heat exchanger manufacturers, petroleum refining units, metal processing & mining industry, nuclear & thermal power plants, oil & gas extraction rigs, aerospace & aeronautical sector, electric motors & pumps, power generation, heavy equipment, agriculture, appliances, ship building, automotive, general industrial, electronics & telecom, infrastructure, military, chemical refining, replacement parts, bridges, construction, electricity, port & harbour, etc.
