Lens Head Screws in Inch Sizes – The Elegant and Secure Fastener for Visible Applications

Whether in automotive engineering, mechanical engineering, boatbuilding, or precision mechanics – lens head screws combine functionality with aesthetics. Their rounded, domed head sits flat on the material and blends in discreetly without protruding excessively . At www.zoll-schrauben.ch, we stock lens head screws in all standard inch sizes – precisely tailored to your projects.

What Makes Lens Head Screws Special?

Lens head screws are a combination of cylinder and round head: slightly flatter than a classic round head, but with a smooth, gently curved surface . They are used wherever a visible yet unobtrusive screw connection is desired – for example, in furniture construction, interior finishing, housing construction, or covers . The wide head also provides a flat contact surface that distributes clamping pressure evenly .

Versatile Drive Types for Every Application

Depending on assembly requirements, we offer cheese head screws with different drive systems:

• Hex Socket (Allen/Inbus) – The classic choice for precise tightening with high torque. Available in designs similar to DIN 7380 . Particularly suitable for mechanical engineering and automotive technology.

• Cross-Recess (Phillips PH / Pozidriv PZ) – The proven drive for quick use with standard screwdrivers . Ideal for assembly and general trades.

• Torx® – The positive-locking drive system for maximum power transmission and minimal wear. Perfect for safety-critical and high-stress connections .

Materials for Every Application

We offer our cheese head screws in inch sizes in various material grades:

• Inox / Stainless Steel A2 (rust-free) – The top choice for outdoor use, marine environments, the food industry, or anywhere corrosion resistance is required . Stainless steel is durable, stable, and maintains its strength even under harsh conditions.

• Zinc-Plated Steel – The reliable and cost-effective standard for use in mechanical engineering, automotive technology, or general trades. The zinc coating provides effective protection against surface rust .

• Uncoated Steel – For applications where subsequent surface treatment (e.g., powder coating or blackening) is planned .

• Spring Steel / Case-Hardened Steel – For applications with high mechanical loads requiring particularly high strength .

Thread Types for Your Specific Application

Depending on the substrate and purpose, we offer our cheese head screws with different thread types:

• UNC (American Unified Coarse) – The American standard thread with coarse pitch, standard in many inch applications .

• Sheet Metal Thread – Self-tapping thread for direct fastening into sheet metal and thin-walled materials .

• Wood Thread – Specially designed for secure fastening in wood and wood-based materials .

Areas of Application at a Glance

Our cheese head screws in inch sizes are suitable for a wide range of uses:

• Automotive and Motorcycle Engineering – For bodywork, panels, add-on parts, and visible bolted connections

• Boats, Ships, and Watercraft – Thanks to rust-free variants, ideal for saltwater environments

• Aircraft Construction and Model Aviation – Precision parts for safety-relevant connections

• Compound Archery and Precision Mechanics – For fine-mechanical adjustments and durable connections

• Mechanical and Plant Engineering – For production systems, conveyor technology, and assembly structures

• Furniture and Interior Construction – For visible, aesthetically pleasing fastenings

• Enclosure and Cover Construction – Where a flat, unobtrusive head shape is required
