Hexagon Head Screw Niczuk M10 x 40 mm, threaded fastener

Hexagon Head Screw Niczuk M10 x 40 mm is a standard metric threaded fastener designed for general mechanical and construction use. With an M10 thread diameter and 40 mm shank length, this hexagon-head screw provides reliable clamping when paired with appropriate nuts and washers. It is intended for joining metal, wood or composite parts in assemblies, frames and repair jobs where a strong, removable connection is required.

Advantages

The hexagon head allows for easy tightening with a wrench or socket, ensuring consistent torque and straightforward installation. Its M10 metric thread supports a wide range of mating nuts and washers commonly used in industrial and household applications. The 40 mm length balances grip and clearance for many standard connections, offering a practical option for through-bolting and component fastening. The screw’s standardized dimensions make it compatible with existing metric fastener systems and facilitate replacements or upgrades.

Suitable for

• Mechanical assemblies and machinery mounting
• Construction joints and metal framing
• Furniture assembly and repair of wooden structures
• Securing panels and composite parts
• General maintenance and replacement of M10 fasteners

Key specifications

• Thread size: M10 (metric)
• Length: 40 mm (shank length)
• Head type: hexagon head for wrench or socket drive
• Application: through-bolt and clamping connections in metal, wood or composites
• Compatibility: intended for use with corresponding nuts and washers

How to use

Select a compatible M10 nut and appropriate washer for the material to be joined. Insert the screw through aligned holes in the components, ensuring shank length provides sufficient thread engagement without bottoming out. Tighten the hexagon head using a properly sized wrench or socket until the required clamp load is achieved; where specified, use a torque wrench to apply the manufacturer-recommended torque. Check alignment and re-tighten after initial load cycles if necessary.

Usage recommendations

For reliable joints, pair the screw with a washer appropriate to the surface and a nut with matching grade or strength class. In corrosive environments or for outdoor use, select compatible corrosion-resistant coatings or stainless alternatives. Avoid over-tightening to prevent thread stripping or material deformation; use recommended torque values for M10 fasteners in the specific base material.
