Product information

Description

Koelner wing bolts DIN 316 M8x40 mm, zinc-plated, pack of 2 are threaded fasteners with a wing-style head designed for manual tightening and quick adjustment without tools. Manufactured to DIN 316 dimensions, each bolt has an M8 threaded shank with a 40 mm overall length and a zinc-plated finish that offers basic corrosion resistance for general indoor and sheltered outdoor applications. These wing bolts are intended for light assembly, fixtures, panels and maintenance tasks where repeated hand-operated fastening and easy removal are required.

Advantages

The wing-style head enables tool-free installation and removal, allowing rapid hand tightening and loosening. Zinc plating provides a protective layer against rust and environmental exposure in typical non-critical conditions. Compliance with DIN 316 dimensions ensures interchangeability with other components specified to the same standard. Supplied as a pack of two, these bolts are convenient for small repair jobs or when paired fasteners are needed for panels and fixtures.

Suitable for

Light furniture assembly and panel fixing
Temporary fixtures and removable covers
Maintenance tasks requiring frequent hand adjustments
Applications where tool-free fastening is preferred

Key specifications

Thread size: M8
Length (shank): 40 mm
Head type: wing-style head for manual tightening
Standard: manufactured to DIN 316 dimensions
Finish: zinc-plated for basic corrosion resistance
Pack quantity: 2 pieces
Material: steel (zinc-plated)

How to use

Insert the threaded shank through the aligned holes of the components to be fastened, then engage with a corresponding M8 nut or into a threaded insert and tighten by hand using the wing head until secure. For increased clamping force, use pliers on the wing edges carefully while avoiding damage to the plating. To remove, reverse the process by loosening the wing head by hand and withdrawing the bolt. Ensure mating threads are clean and undamaged before reuse.

Usage recommendations

Use these zinc-plated wing bolts in indoor or sheltered outdoor environments to avoid accelerated corrosion. For assemblies exposed to persistent moisture, salty air or high mechanical loads, consider stainless or higher-corrosion-resistance alternatives. Store unused bolts in a dry place to maintain the protective finish.
