雙頭牙

一、產品介紹

雙頭牙是一種兩端皆具有螺紋的五金零件，可用於不同零件之間的連接、固定及組裝。

依照不同用途，雙頭牙可設計為：

• 兩端相同螺紋
• 一端木牙、一端機械牙
• 兩端不同螺紋規格
• 中間光桿設計
• 不同長度及牙長

適用於家具、木工、五金、燈具、機械零件及 DIY 等用途。

可依客戶需求提供不同的線徑、長度、牙距、牙長、材料及表面處理，並可依圖面進行客製化生產。

二、雙頭牙使用方式

第一步：確認規格

使用前先確認雙頭牙的：

• 外徑
• 牙距
• 總長
• 兩端牙長
• 木牙／機械牙規格
• 安裝材料

確認規格與配合零件相符。

第二步：安裝第一端

將雙頭牙第一端對準安裝孔，順時針旋入。

如果安裝於木材，建議依木材種類及螺紋尺寸選擇適當的預鑽孔。

第三步：安裝第二端

第一端固定後，將另一端與螺帽、掛鉤、家具零件或其他配件連接。

旋入至適當深度後鎖緊。

第四步：確認固定

確認兩端螺紋都有充分咬合，並檢查組裝後是否有鬆動。

完成後即可進行正常使用。

三、常見用途

四、使用注意事項

1. 安裝前確認螺紋規格是否正確。
2. 木材安裝時，應依材料硬度及螺紋尺寸選擇適當的預鑽孔。
3. 安裝時避免過度施力，以免造成螺紋損傷。
4. 確認螺紋有足夠的咬合長度。
5. 實際承載能力會受到材料、螺紋咬合深度、安裝方式及使用環境影響。
6. 重要或高負載用途應先進行實際荷重測試。
7. 不應超過產品規定或測試的使用荷重。

Double-Ended Threaded Screw

1. Product Introduction

A Double-Ended Threaded Screw is a hardware component with threads on both ends, designed for connecting, fastening, and assembling different components.

Depending on the application, the product can be manufactured with:

• The same thread type on both ends
• Wood screw thread on one end and machine thread on the other
• Different thread specifications on each end
• A plain center shank
• Customized overall length and thread length

Double-ended threaded screws are commonly used in furniture assembly, woodworking, hardware, lighting fixtures, mechanical components, and DIY applications.

Chang Bing can manufacture customized products according to customer requirements, including diameter, overall length, thread length, thread pitch, material, surface finish, and other specifications.

2. Installation Guide

Step 1: Check the Specifications

Before installation, confirm the following specifications:

• Thread diameter
• Thread pitch
• Overall length
• Thread length on each end
• Wood screw thread / machine thread
• Mounting material

Make sure the specifications match the mating components.

Step 2: Install the First End

Align the first threaded end with the mounting hole and turn it clockwise to install.

When installing into wood, an appropriate pilot hole is recommended depending on the type of wood and thread size.

Step 3: Install the Second End

After the first end is securely installed, connect the other threaded end to a nut, hook, furniture fitting, or other mating component.

Screw it to the required depth and tighten securely.

Step 4: Check the Assembly

Make sure both threaded ends have sufficient thread engagement and check that the assembled components are securely fastened without looseness.

The installation is then complete.

3. Typical Applications

4. Usage & Safety Notes

1. Confirm the correct thread specifications before installation.
2. When installing into wood, select an appropriate pilot hole according to the material and thread size.
3. Avoid excessive tightening force to prevent thread damage.
4. Make sure sufficient thread engagement is achieved.
5. Actual load capacity depends on the material, thread engagement depth, installation method, and operating conditions.
6. For critical or high-load applications, actual load testing is recommended.
7. Do not exceed the specified or tested working load.
