Hex Head Bolt Niczuk M16x80 mm, Grade unspecified, threaded metal fastener

Hex head bolt Niczuk M16x80 mm is a threaded metal fastener with a 16 mm nominal diameter and 80 mm shank length designed for mechanical and construction assemblies. The bolt features a standard hexagonal head for wrench or socket engagement and straight metric threads along the shank, intended to be used together with compatible nuts and washers. Its simple, durable design is suited to joining metal or wooden components in structural connections, machinery mounting, and repair work where an M16 hex bolt is required.

Advantages

The hex head design allows easy tightening and removal with commonly available hand tools, providing reliable torque transfer and a secure clamped joint. The metric M16 thread and 80 mm length offer a balance between strength and reach for many assembly tasks. Manufactured as a straightforward threaded fastener, the bolt is versatile and compatible with standard metric nuts and washers, facilitating replacement and maintenance.

Suitable for

• Structural metal-to-metal connections
• Wood-to-metal assemblies where a through-bolt is required
• Mounting machinery, frames, brackets, and supports
• Repair and maintenance tasks in construction and mechanical workshops

Key specifications

• Nominal diameter: 16 mm
• Shank length: 80 mm
• Head type: hexagonal (hex head)
• Thread type: metric straight thread
• Material: metal (steel or equivalent; verify specific grade before use)

How to use

Select a matching nut and appropriate washer(s) for the intended joint and confirm the clamping length accommodates combined material thickness. Insert the bolt through aligned holes in the assembled parts, place the washer and nut on the protruding threaded end, and tighten using a wrench or socket until the required preload or torque is reached. For structural or safety-critical applications, use a calibrated torque wrench and follow specified torque values for M16 fasteners and the material grade in use.

Usage recommendations

Before installation, verify thread compatibility and material grade for the intended application. Use washers to distribute load and prevent bearing damage. For corrosion-sensitive environments, choose appropriate coatings or stainless variants. Replace bolts that show visible wear, thread damage, or corrosion to maintain joint integrity.
