Key features

Raised torx countersunk drywall screw. The cutting teeth under the head cut the board during driving, helping the head sink smoothly into the surface.

Torx drive design creates tight engagement with bits, prevents slipping and reduces bit wear during installation.

Sharp self-tapping point eliminates pre-drilling, the screw can be driven directly into drywall to speed up site work.

The tapered countersunk head sits fully below the board surface after tightening with no protrusion, convenient for subsequent putty filling and wall finishing.

Full thread profile provides firm grip between drywall and keel, delivering strong clamping force and resisting loosening over time.

Multiple surface finishes available to meet anti-corrosion requirements for indoor and outdoor projects.

OEM and ODM Services: Full customization support available based on customer drawings or physical samples.

Free of charge samples are offered for your quality inspection, buyers only need to bear the courier freight.

AI-Powered supplier vetting

SummaryThe supplier demonstrates established export experience, with 90% of sales from exports and 22 years of exporting. It has ISO9001:2015 certification, raw-material traceability, quality assurance, and 100% finished-product inspection, although inspection is performed by packing staff and only two quality inspectors are reported. Customization is broad, covering samples, designs, full customization, minor customization, and flexible customization. Service strengths include in-stock capability, stated lead times within 15 workdays in both peak and off-season, and multiple payment and quotation terms. Limitations include no overseas warehouse, showroom, agent, branch, or overseas service-country coverage, no Fortune 500 cooperation, no new products launched in the last year, one R&D engineer, no popular-brand OEM, and an undocumented corrective/preventive-action process. Financial credibility cannot be assessed because the provided financial figures are excluded from evaluation.

Supplier typeThe supplier is strongly export-oriented, reporting 90% export sales and 22 years of export experience. It can provide in-stock service and accepts FOB, CIF, CFR, and EXW terms, but reports no overseas warehouse, showroom, agent, branch, or overseas service-country coverage.

CertificationsThe supplier reports an ISO9001:2015 certificate for both sustainable development management and management systems, plus other product compliance or sustainability certifications. The specific additional certifications are not identified, so the evidence supports ISO9001 holding but not broader certification strength.

R&D capabilityThe supplier reports one R&D engineer and no new products launched during the previous year. It also reports no available SDK and no popular-brand OEM capability, which indicates limited documented innovation evidence.

Production capacityProduction-related evidence includes raw-material traceability, 100% finished-product inspection, quality assurance, four own-brand quality-control capabilities, inventory capacity, and lead times within 15 workdays in both peak and off-season. Only two quality inspectors are reported, and finished products are checked by packing staff, so production capability is positive but quality-control depth is limited.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization capability.

Product Q&A

Q:What is the advantage of Torx drive compared to Phillips drive?

Torx drives offer higher torque transmission efficiency, reduced slipping (cam-out), and better durability under high torque loads, making them more suitable for automated assembly and heavy-load wood connections.

Q:What is the function of the serrated countersunk head?

The serrated head cuts the board surface during driving, effectively preventing wood splitting and chipping, especially in easily splittable substrates like particleboard and MDF.

Q:Can these screws be used outdoors?

Yes, the grey zinc or Dacromet coatings provide good corrosion resistance, making them suitable for outdoor, humid, and mildly corrosive environments.

Q:What materials are used for these screws?

They are made of premium carbon steel or stainless steel, featuring quenched and tempered heat treatment for high hardness and toughness.

Q:Are samples available?

Samples in stock are free, but freight charges must be collected from the buyer.
