Review: Just the Job. - Excellent quality and value. Arrived an hour ago and used them already. Good range of sizes. Review: Excellent selection and low price - Needed these to fix a damaged exhaust heat shield that the bolts had basically burned away. All I had left was a rough metal pin that there was no way to thread on a new nut or remove the old bolt without damage, the alternative? One of these star-lock washers. I didn’t hold out much hope of it working but as these were plentiful, cheap and something to have handy in the toolbox I ordered the set. Months later and the repair is still holding great. Excellent purchase and easily worth the money. ## Features - 【Premium Material】The washers are made of 65 manganese steel material with smooth edges, which is corrosion-resistant, high and low temperature resistant, and durable for long time use. - 【Easy to Use】The quick speed locking washer exerts a spring force between the fasteners head and the substrate, which maintains the washer hard fixed, creating more friction and resistance to rotation. - 【Easy to Store】All of push-on locking washers are packed in a sturdy transparent plastic case, which is easy to use, find, and carry, can also be used for a storage box. - 【Wide Applications】The internal tooth washers are ideal for machinery equipment, industrial production of shock absorption and insulation, good for quick fixes, and make a repair very simple. - 【What You Will Get】You will receive 340 pcs locking washers, in the size of M3, M4, M5, M6, M8, M10, M12, applicable to different sizes of fasteners, enough for your daily use. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08YXMCV47 | | Best Sellers Rank | 57,639 in DIY & Tools ( See Top 100 in DIY & Tools ) 403 in Washers | | Brand Name | HAOCHEN | | Colour | black/manganese steel | | Compatible Groove Diameter | 2.7 Millimeters | | Country Of Origin | China | | Customer Reviews | 4.5 4.5 out of 5 stars (1,172) | | Fastener Type | Locking washers | | Finish Types | Anti-corrosion | | Item Diameter | 16 Millimetres | | Item Dimensions | 18 x 10 x 2.2 centimetres | | Item Shape | Flat | | Manufacturer | JUNSHEN | | Material Type | 65 manganese steel | | Number of Pieces | 340 | | Screw Head Style | Flat | | Size | M3, M4, M5, M6, M8, M10, M12 | | Thread Size | M3, M4, M5, M6, M8, M10, M12 | | UPC | 692041720858 | | Unit Count | 340.0 Count | ## Product Details - **Brand:** HAOCHEN - **Colour:** black/manganese steel - **Item dimensions L x W x H:** 18 x 10 x 2.2 centimetres - **Material:** 65 manganese steel - **Size:** M3, M4, M5, M6, M8, M10, M12 ## Images ![340 Pcs Internal Tooth Washers, Quick Speed Locking Push On Clips Speed Clips Fasteners Washers Assortment Kit - M3, M4, M5, M6, M8, M10, M12 - Image 1](https://m.media-amazon.com/images/I/718jB9QQqDL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just the Job. *by K***R on 25 August 2025* Excellent quality and value.
