Super quality at a very reasonable price that arrived quickly and in good condition. Now I can get on with my project. Review: Replacement bolts for lawn mower - We bought this to replace a bolt that fell out and got lost from our Mountfield Petrol lawnmower. One of the bolts that held the handle to the main body had fallen off some time ago, and it was quite loose as a result. This fits quite nicely and it is nice and sturdy again. ## Features - Not suitable for replacement in high tensile applications. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B009YHVTFK | | Best Sellers Rank | 166,189 in DIY & Tools ( See Top 100 in DIY & Tools ) 1,728 in Screws (DIY & Tools) | | Brand Name | DBA Hardware | | Colour | Silver | | Country Of Origin | China | | Customer Reviews | 4.4 4.4 out of 5 stars (531) | | Drive System | Internal Hex | | Exterior Finish | Stainless Steel | | Fastener Size | 8mm | | Fastener Type | button | | Finish Types | Glossy | | Grade Rating | A2 | | Head Type | Button | | Item Diameter | 8 Millimetres | | Item Hardness | Grade A2 | | Manufacturer | DBA Hardware | | Manufacturer Grade | Grade A2 | | Manufacturer Part Number | bh0033 | | Material Type | Stainless Steel | | Metal | Stainless Steel | | Number of Pieces | 4 | | Screw Head Style | Button | | Set Name | 4 Pack | | Set Screw Thread Type | Metric Thread | | Size | M8x1.25 | | Thread Class | 3A | | Thread Coverage | Fully Threaded | | Thread Size | M8 | | Thread Style | Right Hand | | Thread Type | M | | UPC | 791429618227 | | Unit Count | 4.0 count | ## Product Details - **Exterior finish:** Stainless Steel - **Head style:** Button - **Manufacturer grade:** Grade A2 - **Material:** Stainless Steel - **Thread size:** M8 ## Images ![8mm Button Head Bolts / Screws (4 Pack) M8 x 20mm A2 Stainless Steel Socket Allen Key Dome Head Bolt Free UK Delivery - Image 1](https://m.media-amazon.com/images/I/21KfXZuLaDL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Superb s/s button head set screws *by J***J on 13 February 2026* Just what I needed.
