M8 x 20mm Flanged Hex Head Bolts Mellewell DIN 6921 20pcs

Description

Product Overview

The M8 x 20mm flanged hex head bolt from Mellewell is a precision‑engineered fastener designed for demanding industrial and DIY applications. Constructed from premium stainless steel grade 304, the bolt offers outstanding resistance to rust, chemicals, and harsh environmental conditions, ensuring a long service life even in marine or outdoor settings. The flanged head, conforming to DIN 6921 specifications, features a 13mm diameter head and an 18mm hex washer that distributes load evenly, reducing stress on the material being joined and preventing deformation. With a pitch of 1.25mm and a total length of 20mm (excluding the head), the bolt provides a secure, tight fit for a wide range of components, from electronic housings to mechanical assemblies. The product is supplied in a convenient pack of 20 pieces, making it ideal for bulk projects, inventory stocking, or repeat‑order convenience.

Beyond its robust construction, the bolt’s design incorporates a smooth, rounded flange that simplifies installation with standard hex wrenches or socket sets, reducing the risk of stripping or rounding off the fastener during tightening. The stainless steel material also offers a clean, professional appearance, which is particularly valuable in visible applications such as furniture assembly or consumer electronics where aesthetics matter. The product meets rigorous DIN 6921 standards, guaranteeing dimensional accuracy and consistent performance across every unit in the pack.

Usage

These flanged hex head bolts are exceptionally versatile and can be employed across a broad spectrum of industries and everyday tasks. In the home environment, they are perfect for securing appliance components, assembling flat‑pack furniture, and repairing garage tools. Their corrosion‑resistant properties make them suitable for outdoor projects such as garden equipment, patio furniture, and marine hardware where exposure to moisture is inevitable.

In industrial settings, the bolts excel in applications that demand reliable fastening under vibration and load, including machinery frames, control panels, and communication equipment enclosures. The flanged head provides a larger bearing surface, which is advantageous when fastening thin sheet metal or plastic components, as it prevents pull‑through and distributes stress evenly. Additionally, the stainless steel composition ensures that the bolts maintain their strength and appearance even after repeated cycles of tightening and loosening, making them a cost‑effective choice for maintenance and repair work.

For professional technicians and engineers, the M8 flanged bolts simplify inventory management because the 20‑piece pack aligns with common project quantities, reducing the need for multiple orders. Their compliance with DIN 6921 also means they can be seamlessly integrated into existing design specifications and engineering drawings without the need for custom modifications.
