Machine Screw Thread & Anti-Cross Threading Screws
Valley Fastener Group manufactures a broad variety of thread types to suit diverse applications, including:
- Machine Screw Threads
- Tapping Screw Threads
- Tri-Lobular Threads
- Thread-Forming Threads
- IFI-standard threads such as Type AB, B, BF, BP, C, CA, G, U, 1, 23, 25
What Are These Thread Types?
- Machine Screw Threads - Precision-start threads designed for tight, matched engagement with nuts or tapped holes, ensuring secure application with controlled torque and reusability.
- Tapping Screw Threads - Engineered to cut their own mating threads in softer materials like plastic or thin metal, enabling installation without pre-tapping and allowing faster assembly.
- Tri-Lobular Threads - Triangular-shaped threads that compress radially as they’re driven into a hole, creating interference for superior thread retention. They improve pull-out strength and reduce stripping in soft substrates.
- Thread-Forming (Roll) Threads - Rather than cutting, these threads plastically deform the material to form the mating profile, resulting in stronger threads with better fatigue resistance, smoother textures, and minimal material loss.
- IFI-Standard Threads (Types AB, B, BF, BP, C, CA, G, U, 1, 23, 25) - Standard thread forms and pitch variations governed by the Industrial Fastener
Benefits of These Thread Types
- Enhanced Strength & Fatigue Resistance - Thread-forming and tri-lobular threads deliver better structural integrity and fatigue life compared to conventional cut threads.
- Improved Retention in Soft Materials - Tri-lobular and tapping screw threads excel in plastics or light materials, resisting pull-out and enhancing fastening reliability.
- Efficient Assembly - Tapping screws eliminate pre-tapping, speeding up assembly. Thread-forming and tri-lobular threads also reduce or eliminate torque variation and improve consistency.
- Compatibility & Standardization - Machine screw and IFI standard threads ensure seamless integration with existing designs and tooling, promoting interchangeability.
