Baks fastener set M8x14 mushroom-head screw with serrated flange nut, pack 100 – model 651241

Set of Baks fasteners consisting of M8x14 mushroom-head screws with serrated flange nuts, 100 pieces, model 651241. The mushroom (rounded) head provides a low-profile, smooth bearing surface while the serrated flange nut adds a locking feature that resists loosening from vibration. This fastener set is intended for mechanical and assembly use where secure, low-profile joints are required between metal-to-metal or metal-to-plastic components in construction, furniture and equipment assembly.

Advantages

The mushroom-head screw offers a reduced snag risk and a finished appearance while still delivering reliable clamping force. The serrated flange nut distributes load over a larger area and its serrations bite into the mating surface to improve resistance to rotational loosening. Supplied in a pack of 100, the set provides consistent parts for repetitive assembly tasks and reduces the need for frequent reordering.

Suitable for (tasks / use cases)

• Securing panels and fittings in furniture assembly
• Fastening brackets and small components in construction frames
• Joining metal or plastic housings in equipment assembly
• Applications where vibration resistance and a low-profile head are required

Key specifications

• Thread size: M8
• Screw length: 14 mm (threaded portion)
• Head type: mushroom (rounded) head for low profile
• Nut type: serrated flange nut for locking and load distribution
• Material: steel (suitable for general mechanical fastening) — surface finish may vary
• Pack quantity: 100 fasteners (screws and matching nuts)

How to use

Match the M8 screw and serrated flange nut to the corresponding tapped hole or use with a matching M8 clearance hole and nut on the opposite side. Insert the mushroom-head screw through the parts to be joined, fit the serrated flange nut on the exposed thread and tighten using the appropriate wrench or socket until the joint is secure. Avoid over-tightening to prevent damage to softer materials; the serrations on the nut are intended to engage the mating surface to reduce loosening under vibration.

Usage recommendations

For best results, use on clean, suitably hardened or reinforced surfaces. When fastening into softer materials, consider using a washer under the mushroom head or reinforcing the mating area to distribute load and prevent pull-through. For corrosive environments, select an appropriate corrosion-resistant finish or coating.
