Quick Overview

A washer with serrations that extend radially inward or outward to bite into the bearing surface. This type of washer is especially effective as a lock washer when used with a soft substrate, such as aluminium or plastic, and can resist rotation more than a plain washer on hard surfaces, as the tension between washer and the surface is applied over a much smaller area (the teeth). There are four types: internal, external, combination, and countersunk. The internal style has the serrations along the inner edge of the washer, which makes them more aesthetically pleasing. The external style has the serrations around the outer edge, which provides better holding power, because of the greater circumference. The combination style has serrations about both edges, for maximum holding power. The countersunk style is designed to be used with flat-head screws. Bulk material handling equipments can provide Cold Forged & Hot ForgedStar Washer / Non Standard Special Star Washer with complete material compliance as both Metric & Imperial Inch sizes. Types of coating for star washer / non standard special star 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. Star Washer / Non Standard Special Star 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 Bronze Alloy: LEADED GUNMETAL ALLOY LG1, LEADED PHOSPHOR BRONZE ALLOY LPB1, 932, 544, MANGANESE BRONZE ALLOY 675, LEADED GUNMETAL ALLOY LG2, GUNMETAL ALLOY G1, G3, 903, 938, PHOSPHOR BRONZE ALLOY 510, PB1, PB2, NAVAL BRASS ALLOY 464, SILICON BRONZE ALLOY 651, 655, 613, B16 BRASS, LEADED BRONZE ALLOY LB1, LB2, LB3, LB4, LB5 Aluminum: Alloy 7075, 6061, 2024
