What types of fasteners does YH Fastener manufacture?

We manufacture machine screws, self tapping screws, sealing screws, shoulder screws, sems screws, captive screws, security screws, nylon patch screws, carbide insert screws and set screws, plus hex keys, Torx keys and spring and ball plungers, in both standard and custom versions.

Can you produce non-standard screws from my drawings?

Yes. Our engineering team reviews 2D drawings, 3D models or physical samples, confirms material, head style, drive, thread and finish, and then builds tooling for cold heading and thread rolling. Non-standard and international-standard parts are both supported.

Which quality certifications does your factory hold?

Our production system operates under ISO 9001, ISO 14001 and IATF 16949. Every batch passes multi-stage inspection from incoming wire rod to final packing, and inspection records can be provided with shipments.

How do you prevent screws from loosening under vibration?

Depending on the application we recommend pre-applied nylon patches, sems screws with captive washers, or shoulder and sealing designs. The right solution is selected based on joint material, required re-use cycles, torque and operating temperature.

Do you export to my country and how do I start a project?

YH Fastener ships to more than 60 countries. Request our catalog or contact our sales engineers with your drawing, quantity and target application, and we will reply with a technical review within 24 hours.

Common Pain Points in Actual Assembly

Many purchasers encounter recurring troubles during mass production when applying self tapping screws. High screw driving torque leads to tool wear. Thin plastic shells crack after fastening. Insufficient pull‑out strength causes loose connections after long‑time operation. Most of these issues are not caused by raw screw quality, but improper type selection and parameter matching. Our self tapping screws are developed targeting these real‑world assembly pain points. Thread profile hardness and surface condition are controlled to fit different substrate materials.

Thread Difference Solves Different Substrate Problems

Thread-cutting self tapping screws adopt a special thread flute design. It cuts material chips when screwing into hard thin metal and composite plates. It fits rigid substrates where thread forming cannot work well.

Thread-forming self tapping screws displace material without generating chips. It greatly lowers plastic cracking risk for thin plastic housings during high‑speed continuous assembly. This type is widely chosen by consumer electronics manufacturers.

Material and Surface Treatment Against Corrosion Risk

Indoor general assembly projects can adopt zinc‑plated carbon‑steel self tapping screws. It balances cost and basic rust resistance.

For damp working environment or outdoor installation, choose 304 or 316 stainless‑steel self tapping screws. It avoids joint failure caused by rust. Black oxide finish is only suitable for completely dry indoor environment, its anti‑corrosion performance is limited. Special coatings can be customized according to your working conditions.

Practical Installation Reminders for Buyers

Pilot hole diameter directly decides final fastening performance of self tapping screws. Too small holes raise driving torque and crack work pieces. Too large holes reduce holding force. You need to confirm hole size combined with your actual material hardness. We can provide reference hole data after knowing your substrate. Do not confuse self tapping screws with self‑drilling screws, self‑tapping series must use pre‑drilled pilot holes.

About Our Factory

We are a professional fastener manufacturer producing large batches of self tapping screws and other standard and non‑standard fasteners. We own complete cold heading thread rolling and in‑house testing equipment. Before bulk delivery each batch will pass dimension hardness and surface inspection. Our technical team can give targeted fastening suggestions according to your assembly difficulties, helping you reduce defect rate on production lines.

Custom Solution Service

Standard sizes cannot cover all project demands, so we provide custom service for self tapping screws. Adjust head shape thread specification length and surface treatment following drawings or physical samples. Small batch trial production is supported before mass order. Test fastening effect on your real work piece to prevent mass loss risk. Send your requirement and we will reply with quotation and lead time.

Frequently Asked Questions

Q1: Can self tapping screws work without pilot holes?

No. Self tapping screws require pre‑drilled pilot holes. They differ from self‑drilling screws. Operating without pilot holes will cause excessive torque and result in broken screws.

Q2: Which option to select for plastic housing assembly?

Thread‑forming self tapping screws are preferred. They displace material without creating cutting chips, which significantly lowers the risk of thin plastic shells cracking during high-speed assembly.

Q3: What material fits outdoor application?

304 or 316 stainless‑steel self tapping screws are recommended. Standard zinc‑plated carbon steel will rust under long‑term outdoor exposure or damp environments.

Q4: When should thread-cutting screws be used instead of thread-forming?

Thread-cutting screws are ideal for hard thin metal and composite plates. Their special flute design actively cuts material chips, ensuring secure engagement in rigid substrates where thread forming cannot work well.

Q5: Is black oxide finish suitable for outdoor or damp environments?

No, black oxide finish provides limited anti-corrosion protection and is only suitable for completely dry indoor environments. Outdoor or damp applications should use stainless steel or specialized coatings.

Q6: Do you provide custom dimensions and trial production runs?

Yes. We accommodate custom head shapes, drive types, thread profiles, and finishes based on drawings or physical samples. Small batch trial production is supported so you can verify fastening performance on actual substrates before volume production.
