Applications & Industries

PEEK Engineering Plastic Micro Countersunk Screws are bought for a small number of well-defined jobs. These are the ones we ship them for. Stocked from M1.2 to M1.6.

Industries that specify PEEK Engineering Plastic Micro Countersunk Screws

Prototype assemblies Countersunk plastic screws avoid a metal head near the component.
Insulated electronics Engineering-plastic screws provide a nonconductive threaded joint in a compact package.
Vacuum and analytical equipment Low-outgassing plastic is used around sensitive instruments.
Chemical equipment PEEK resists service environments where ordinary metal hardware may be unsuitable.
Automotive & transport Chassis, driveline and body fixings that see vibration and are assembled to a controlled preload.
Steel fabrication Bolted connections in frames, enclosures, walkways and weldments, on the bench and on site.

Typical applications

using the 90-degree head seat and No. 0 recess
providing electrical insulation with a miniature countersunk screw
checking the documented break loads instead of borrowing metal-screw torque
matching the plastic screw to the parent thread without over-driving it
joints where the property class is stated on the drawing
clamping two machined faces to a calculated preload

Service conditions to specify against

Marine and coastal: Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
High load: Supplied in ISO 898-1 property classes, so the joint can be designed to a stated proof load and tightened to a calculated torque rather than by feel.
Torque and preload: The joint is designed around bolt tension, so lubrication, coating and the friction coefficient all change the torque figure — state them together.

Where to use something else

Do not substitute metal-fastener torque for the plastic break-torque example; over-driving can fracture the screw.
Do not use a machine thread into unthreaded sheet or timber; use a tapping screw, rivet nut or insert made for that parent material.

PEEK Engineering Plastic Micro Countersunk Screws (Trade series (PEEK micro screws)) are a type of screws used across industrial assembly. Below is the complete size table together with material, standard and application guidance.

What Are PEEK Engineering Plastic Micro Countersunk Screws?

PEEK Engineering Plastic Micro Countersunk Screws are screws defined by Trade series (PEEK micro screws). They are selected by thread size and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.

Materials & Finishes

Common materials include carbon steel (typically zinc plated or hot-dip galvanized), alloy steel in property classes 8.8, 10.9 and 12.9, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, property class and surface finish appropriate to your load and environment.

Pricing

PEEK Engineering Plastic Micro Countersunk Screws are supplied to order. Pricing starts from approximately US$0.080 per piece for standard sizes in carbon steel; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.

Inside the plant

Manufactured in our own plant

This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.

01

Cold heading

Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.

Head dimensions and under-head radius checked at set-up and per shift.
02

Thread rolling

Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.

Go / no-go ring gauges to ISO 965 tolerance class 6g.
03

Heat treatment

Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.

Core hardness and tensile tested per lot to ISO 898-1.
04

Surface treatment

Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.

Coating thickness and neutral salt spray hours to ISO 9227.
