Phillips Screw Manufacturers

Our Phillips Screw Range

The range is organized by head geometry and governing standard, so a project can be specified from a single reference number rather than a description. Metric series follow DIN and ISO practice; inch series follow ASME/ANSI B18.6.3.

Where a project needs a different drive or head, we also produce Bolts and matching Nuts so a complete joint can be supplied from one source.

How the Cross Recess Behaves on the Line

The angled recess walls guide the bit into engagement without manual alignment, which shortens cycle time on power drivers and robotic spindles. The same geometry lets the bit cam out once torque exceeds the intended level, so the screw acts as a passive limiter rather than transferring excess load into the thread or the workpiece surface.

• Drive size: recess number must match the bit; a worn or undersized bit rounds the recess before reaching target torque.
• Bit condition: cam-out depth and recess life depend on bit wear, so consumable control matters as much as screw tolerance.
• Clamp load: for a given torque, thread pitch and lubrication determine the preload actually achieved in the joint.
• Seating: countersunk and oval heads require a matching countersink angle to sit flush without deforming the panel.

Materials, Finishes and Specification Choices

Carbon steel and stainless steel cover most Phillips screw applications. Selection follows the corrosion exposure, the mating material and the torque the assembly can tolerate.

Sizes, Threads and Configuration Options

We produce standard catalogue sizes and drawing-based variants. The variables below are the ones that most often change between projects.

• Diameter and length: metric and inch series, with length measured under head unless the drawing states otherwise.
• Thread: coarse or fine pitch, fully threaded or partially threaded shanks.
• Point: flat, chamfered or pilot point for sheet and plastic engagement.
• Head: pan, round, countersunk, oval countersunk, truss, fillister, spherical seat and heavy hex.
• Finish: plain, zinc plated, black oxide, hot-dip galvanized or stainless passivation.
• Assembly: screws can be supplied with captive washers or as part of a fastener assembly.

Quality Control and Acceptance

Production follows total quality management with inspection after each process and final inspection of finished goods against the agreed standard or drawing. Our laboratory is equipped with a spectrometer, coordinate measuring machine and X-ray flaw detector, covering chemical composition, mechanical properties, non-destructive testing and geometric dimensions.

For a project order we agree the inspection items, sampling basis and record format before the first batch, so acceptance at goods-in matches what was verified at our works. Certificates of conformity and material records are issued with the shipment where the contract requires them.

Packaging, Delivery and Documentation

Fasteners are supplied in retail kits, blister packs, custom boxes and export cartons, with labelling matched to the sales channel or the line-side kanban. Sea freight is the standard mode from Shanghai and Ningbo, both within a short drive of our operations; air freight can be arranged for urgent requirements.

Documentation typically includes the packing list, material or conformity records and inspection reports. Where a distributor needs private-label cartons or barcoded inner packs, the artwork and label data are confirmed before packing starts.

Information We Use to Configure Your Solution

A workable quotation needs the joint, not just the part number. The following inputs let us fix material, head form, tolerance and packing without a second round of questions.

Custom Development and Project Support

Customized production is core to what we do. Our engineering team develops parts from drawings or samples, including non-standard head forms, special lengths and application-specific thread configurations. With more than 100 employees, over 10 engineers and more than 50 technical staff, we can follow a project from sample approval through series production.

Annual output exceeds 20,000 tons across 12 production lines, including a fully automatic shell molding line and four heat treatment lines, which supports both large programmes and small and medium batch purchases. Our products are exported to more than 30 countries, with North America and Australia among the principal markets.

Frequently Asked Questions

Which Phillips screw head forms can you supply?

We produce pan, round, countersunk, oval countersunk, truss, oval fillister, spherical seat cap and heavy hex head forms, in metric sizes to DIN and ISO references and inch sizes to ASME/ANSI B18.6.3.

Can you manufacture to our drawing rather than a catalogue standard?

Yes. We develop and manufacture from drawings or samples, including special head geometry, non-standard lengths, specific thread pitches and defined coating thicknesses.

How is quality verified before shipment?

Inspection is carried out after each production process, and finished goods are inspected against the agreed standard or drawing. Chemical composition, mechanical properties, non-destructive testing and dimensions are checked with laboratory equipment including a spectrometer, CMM and X-ray flaw detector.

What packing options are available for distribution?

Retail kits, blister packs, custom boxes and export cartons are all available, with labelling and barcoding matched to the sales channel or line-side consumption.

How quickly do you respond to an enquiry?

Enquiries received on working days are answered within 12 hours, and trade terms such as FOB or CIF are confirmed at quotation stage.
