M10 x 80mm Flanged Hex Head Bolts with Nuts & Washers - Durable 20pc

In this review the M10 x 80mm flanged hex head bolt kit is evaluated for workshop and marine use; the single biggest reason to buy is its corrosion-resistant 18-8 (304) stainless steel construction combined with a complete fastening set. The pack of 20 bolts, plus matching flange nuts and both flat and lock washers, aims to simplify small projects and repairs by providing a uniform, fully threaded M10 solution that resists rust better than ordinary steel fasteners.

Key Features

• Material: 18-8 (304) stainless steel offers enhanced corrosion resistance and a longer service life in humid or outdoor environments.
• Complete kit: Twenty bolts plus matching flange nuts and both flat and lock washers mean fewer trips to the store and consistent hardware for a multi-fastener job.
• Fully threaded shaft: The full-length threading on the 80mm screws gives flexibility for clamping varying material thicknesses and for use with longer assemblies.
• Flanged head design: The 22mm flanged head distributes load and reduces the need for a separate washer under the head in many applications.
• Standard sizing: M10 thread diameter with 1.5mm pitch matches common metric hardware standards for easy replacement and compatibility.

Who It's For

This kit is a good fit for home DIYers, small workshops, and maintenance teams who need a reliable, corrosion-resistant metric fastener set for furniture, equipment, or light marine applications. The full threads and included hardware make it practical for jobs that require consistent clamping and replacement parts across multiple fasteners.

Users needing specialty high-strength or aerospace-grade bolts should look elsewhere, as these parts are standard 18-8 (304) stainless steel intended for general-purpose durability rather than extreme structural loads.

Pros & Cons

Pros

• Durable 18-8 (304) stainless steel construction resists rust and extends service life.
• Value pack includes 20 bolts, flange nuts, flat and lock washers for convenience and consistency.
• Flanged head and full threading improve load distribution and clamping versatility.

Cons

• Finish reports are mixed between powder coated and painted steel by some users, so appearance may vary.
• Not intended for high-tensile structural applications where specialty grades are required.
