Custom-Made Non-Standard Screws

Customized non-standard screws are specially designed for special needs and can be customized with free materials (carbon steel/stainless steel, etc.), size, head shape, thread and surface treatment (such as galvanizing, Jiumeit, etc.). Suitable for special assembly scenarios in the machinery, automobile, electronics and other industries, meeting the requirements of high strength, corrosion-resistant or special-shaped structures. Supports drawing and sample processing, providing accurate solutions to ensure perfect matching with the equipment. Fast delivery and reliable quality, it is ideal for replacing standard parts.

Features:

Customized special sizes (such as length, diameter, pitch, etc.)

Customized special-shaped structures (such as large heads, steps, grooves, threads)

Customized various materials (carbon steel, stainless steel, titanium alloy, brass, copper, aluminum)

Customized various surface treatments (galvanized, nickel-plated, blackened, Jumet, Darkro)

Customize various special functions (anti-loosening, high temperature, corrosion resistance)

Core advantages:

FAQ

Q1: What information is needed to customize non-standard parts?

A1: Detailed drawings (marked size/tolerance/material), surface treatment requirements, performance standards, or samples are required for reproduction.

Q2: How long does it take from design to shipment?

A2: It depends on the type of product to confirm. The time required to reopen the mold is about 7-15 days, and the time required to be released is about 3-7 days.

Q3: How to ensure the thread accuracy of non-standard screws?

A3: Can be processed by CNC turning or rolling, combined with thread stop gauge detection, the accuracy can reach ISO 4H/6g level

Q4: Why is the unit price of small batch customization (1000-10000 pieces) higher than that of large batches?

A4: Small batches require separate adjustment of the machine and replacement of molds. The cost of the sharing cost can be evenly allocated by more than 50,000 pieces, and the price reduction is 30%-50%.

Q5: Can existing molds be modified instead of a brand new mold opening?

A5: Similar product molds can be evaluated (such as square head to step head), saving 50% of mold costs, but modification costs are required.
