This assortment is designed for repairs involving different metric thread sizes. It includes 900 split spring lock washers in 304 stainless steel, organized across nine sizes from M2 to M12. Keep it on hand for matching screws, nuts, and bolts in household, shop, automotive, or marine work. ## Quick overview These spring lock washers are made from 304 stainless steel with a polished silver finish. Their split design adds a spring element to a threaded fastening, while the washer’s bearing surface helps spread the load beneath a nut or bolt head. That makes the kit useful when assembling or maintaining connections where helping to resist loosening is important. The assortment covers M2, M2.5, M3, M4, M5, M6, M8, M10, and M12. It contains 200 each of M2, M2.5, and M3, 100 M4, 82 M5, 50 each of M6 and M8, 10 M10, and 8 M12 washers. The different quantities let you draw on the sizes most commonly needed in small fastening tasks while keeping larger sizes available for occasional jobs. The washers are supplied in a plastic case to keep the assortment together between projects. ## Tips for day-to-day use Match the washer size to the threaded fastener: this kit is intended for screws, nuts, and bolts of the corresponding sizes. For example, when servicing an appliance connection that uses an M4 bolt, select an M4 washer rather than choosing by appearance alone. Keeping the pieces grouped in their case also makes it easier to find the size needed for a repair or assembly. The 304 stainless steel material is described as corrosion-resistant, including in humid conditions and in high or low temperatures. This makes the washers relevant to a range of settings such as automotive and marine applications, household and commercial appliances, and shop or building projects involving decks and fences. Small parts should be kept away from children under three. ## Practical tips Before assembly, identify the thread size of the screw, nut, or bolt and select the matching washer. Use the washer as part of a threaded fastening where its load-spreading bearing surface and spring-lock design suit the task. The assortment is a practical fit for a workbench that handles varied repairs: one project may call for smaller appliance hardware, while another may need a larger fastener for automotive or building work. If your work is consistently limited to one fastener size, a single-size supply may better match that routine. For mixed maintenance and assembly, having nine metric sizes in one kit offers more flexibility without needing to source each size separately. Its range also makes it useful to keep with general repair supplies for household, electrical, automotive, and marine tasks. ## Should you buy it? Choose this HELIFOUNER kit if your projects use several metric fastener sizes and you want split lock washers made from 304 stainless steel in one organized assortment. The range from M2 through M12, varied piece counts, and plastic case support routine repairs and assembly work across appliances, automotive or marine connections, and shop projects. It is especially suited to keeping a selection of matching washers close at hand when the fastener size changes from job to job. ## Images ![HELIFOUNER HELIFOUNER---Lock---Washer Spring Lock Washer Kit, 304 Stainless Steel — 1](https://www.ofertitastop.com/i/N9thuTbs2-pdecKGQyOr6UxkmdlhT6_2UunRYH5x4nuNadENsr4uMBhrC9N3sr8_Pm4UhuNCDWmhxrFpkiugYyaL0QeI8N0sTS6Zmio1hrXI3DIzPDeE3A.jpg) ![HELIFOUNER HELIFOUNER---Lock---Washer Spring Lock Washer Kit, 304 Stainless Steel — 2](https://www.ofertitastop.com/i/QDWlj78Cb0GfBgno9zQkESuPxLs0miR9g6vh3vUZpjq6QobtSYnVR1ZOXL5cloRCpRNSODVLifL2tF8GP4nRdAlorLhPOmOCumycK-0r2cpgcQR5aULEgw.jpg) ![HELIFOUNER HELIFOUNER---Lock---Washer Spring Lock Washer Kit, 304 Stainless Steel — 3](https://www.ofertitastop.com/i/j_0RFHq8pL2gJDvbxQa2n2U_ynDREgGsqg5UJz2eaCxHj3HdmD022_7b9nywsMen-GvZtOyp6lBVGpYnyP3Lv_M1Wl8M6JoDdc3kljPcC2toU1F0sc6-Dw.jpg) ![HELIFOUNER HELIFOUNER---Lock---Washer Spring Lock Washer Kit, 304 Stainless Steel — 4](https://www.ofertitastop.com/i/HmxLKeNaqxzU0ECyUhw3_8-M5YPMWbBQQwB-aI3YJ31FFrREA-ksusfW7mFgQR6JhR2M6_bXNa34RBPWvuwnR1uqUw25HqNEx6A1F1szuYk271q0XMMUYA.jpg) ![HELIFOUNER HELIFOUNER---Lock---Washer Spring Lock Washer Kit, 304 Stainless Steel — 5](https://www.ofertitastop.com/i/-IiEygPnwYSaQJfjLISzz3KKP3gRzcU7l5DhPxKhmpwuamJ2oU0EHl4yfXHc8psZqZ7QaHBFolNOydhnzTNQFaYVVn_5MRQuLWYtAi30X489Kd8JqBkvJg.jpg)
