As a trusted supplier from Hefei SENOTECH New Materials Co., Ltd (established 2020, annual export US$1–1.5 million), we are proud to offer premium wholesale chipboard screws with Pozi drive, half thread, and yellow zinc plated finish. These screws are engineered to deliver exceptional holding power in chipboard, MDF, and solid wood applications without the risk of snapping. With full size availability and high hardness through induction hardening, our screws meet the rigorous demands of professional woodworkers, construction contractors, and furniture manufacturers worldwide.
Our chipboard screws are manufactured using high-quality hardened steel and feature a Pozi (PZ) drive recess that provides superior bit engagement, reducing cam-out and allowing faster driving. The half-thread design ensures efficient chipboard compression while maintaining strong pull-out resistance. The yellow zinc plating offers reliable corrosion protection for indoor applications. Below we detail the key technical specifications and advantages.
Key Features & Benefits
- Pozi Drive Recess: Increased torque transfer with minimal bit slippage – ideal for power tools.
- Half Thread Design: Optimized for chipboard: the smooth shank reduces friction while the thread section bites firmly, preventing material splitting.
- Yellow Zinc Plated: Provides moderate corrosion resistance for dry indoor environments; small batch trial available upon request.
- High Hardness (Induction Hardened): Achieves core hardness of 450–550 HV, ensuring the screw withstands high torque without snapping.
- No Snapping Performance: Specialized heat treatment eliminates brittle fractures during installation.
- Full Size Availability: From 3.0 x 12 mm up to 5.0 x 60 mm (metric) or equivalent imperial sizes – all stocked for fast delivery.
- Countersunk Head: Flush finishing for a clean, professional appearance in finished products.
- Customizable Options: Colors, packaging (bulk or retail), and length tolerance are configurable per order.

Why Choose SENOTECH Chipboard Screws?
We understand that in woodworking and construction, fastener reliability directly impacts product quality and assembly efficiency. Our chipboard screws are manufactured under strict process control to ensure every unit meets consistent hardness, thread geometry, and plating uniformity. The half-thread design reduces driving torque by minimizing friction in the upper shank, allowing faster installation while still delivering strong pull-out resistance in the threaded portion. The Pozi drive recess provides four contact points for better bit engagement compared to Phillips, reducing strip-outs and operator fatigue. Additionally, the yellow zinc plating provides a visually appealing finish that blends with many wood tones, while offering reliable protection against oxidation during storage and normal indoor use.

Frequently Asked Questions
-
Q1: What is the hardness of these chipboard screws? How do they prevent snapping?
A: Our screws achieve a core hardness of 450–550 HV and surface hardness of 550–650 HV through precise induction hardening. The heat treatment process is carefully controlled to eliminate brittle microstructures, ensuring the screw flexes slightly before snapping – virtually eliminating breakage during normal installation. -
Q2: Can these screws be used for outdoor applications?
A: The yellow zinc plating provides moderate corrosion resistance mainly for indoor use (dry environments). For outdoor or high-humidity applications, we recommend our stainless steel or hot-dip galvanized options – please inquire for details. -
Q3: What sizes are available for wholesale purchase?
A: We offer a full range from 3.0 mm to 5.0 mm (metric) and #6 to #12 (inch), with lengths from 12 mm to 60 mm. For bulk orders, we can also supply non-standard lengths with a minimum order quantity (MOQ). -
Q4: Are Pozi (PZ) bits included with the screws?
A: Typically bits are not included, but we can provide matching PZ bits as a separate or bundled purchase. Please let us know your requirement when ordering. -
Q5: What is the difference between half thread and full thread chipboard screws?
A: Half-thread screws have a smooth shank near the head, reducing friction and preventing the screw from over-tightening into chipboard, which can cause splitting. Full-thread screws are better for metal-to-wood or when maximum pull-out strength is needed in softer materials. Our half-thread design is optimized specifically for chipboard and particleboard. -
Q6: Do you offer samples before bulk order?
A: Yes, we provide free samples (customer pays shipping) for evaluation. Once you approve the quality, we can proceed with bulk production. Contact our sales team to arrange. -
Q7: What is the packaging for wholesale orders?
A: Standard packaging is 1000 pcs per cardboard box, with multiple boxes per pallet. Custom packaging (e.g., retail blister packs, poly bags with your logo) is available at additional cost with MOQ. -
Q8: How long does shipping take to North America / Europe?
A: For in-stock sizes, we can ship within 7–10 days after payment. Air freight takes 5–7 days, sea freight typically 20–30 days depending on destination. We work with reliable logistics partners to ensure timely delivery.
