Screws Celo 940TG universal self-tapping 5.5x35 mm TG Tornigrap CNBOP pack of 100

Celo 940TG universal self-tapping screws 5.5x35 mm with TG Tornigrap head design and CNBOP surface finish are intended for general-purpose fastening in construction, wood and thin metal assemblies. Supplied in a pack of 100, these screws combine a universal thread form with a head engineered for reliable driver engagement and reduced cam‑out. The CNBOP coating provides corrosion resistance appropriate for common indoor and semi-exposed applications.

Advantages

These screws offer consistent thread cutting and secure hold across a range of base materials, minimizing the need for pre-drilling in many instances. The TG Tornigrap head improves bit seating and torque transfer for faster installation, while the CNBOP finish helps protect the fastener against surface corrosion. The 5.5x35 mm size balances shear strength and penetration depth for typical carpentry and light structural tasks.

Suitable for

• Joining wood-to-wood connections in interior and semi-exposed constructions
• Fastening thin sheet metal to wooden supports where self-tapping is required
• General carpentry, furniture assembly and joinery tasks
• Repair and maintenance jobs requiring a pack of identical fasteners

When it may not be suitable

These screws are not intended for heavy structural connections where certified high‑strength fasteners are required. The CNBOP coating offers moderate corrosion resistance but is not equivalent to stainless steel or specialized marine coatings for prolonged outdoor or coastal exposure. For very hard materials or thick steel sections, pre-drilling or a different fastener type may be necessary.

Key specifications

• Length: 35 mm
• Thread diameter: 5.5 mm
• Head type: TG Tornigrap drive for improved bit engagement
• Finish: CNBOP surface coating for basic corrosion protection
• Function: Universal self-tapping thread suitable for wood and thin metal
• Package quantity: 100 pieces

How to use

Select an appropriately sized driver bit that matches the TG Tornigrap head. Position the screw perpendicular to the workpiece and start at low speed to ensure correct seating of the bit. Drive the screw until the head is flush with or slightly below the surface, taking care not to over-torque which can strip the thread or damage the material. For harder substrates or thicker metal, consider pilot drilling to prevent thread damage and ensure accurate alignment.

What to consider before purchase

• Compatibility of the 5.5 mm diameter and 35 mm length with your materials and joint design
• Whether the CNBOP coating provides sufficient corrosion protection for your environment
• Tooling: availability of the correct TG Tornigrap driver bit
• Quantity needed – pack contains 100 screws

Usage recommendations

Use in interior and light exterior applications where moderate corrosion resistance is acceptable, and match driver bit size to the TG Tornigrap head for efficient installation. For prolonged outdoor exposure or highly corrosive environments, choose stainless or specially coated fasteners.
