Product Description

One slot screw is one of the most common types of screws, named after a straight groove on the head. The following describes its structural characteristics, application scenarios, advantages and disadvantages:

• Structural features

Head: Common shapes include pan head, countersunk head, semi-circular head, etc. The surface is flat and smooth, and the depth and width of the groove depend on the screw specifications. Generally, the groove width is between 1-5 millimeters, and the depth is related to the height of the head. It is usually necessary to ensure that the screwdriver can be stably inserted and effectively transmit torque.

Screw: The shaft is cylindrical in shape, with a sharp conical end for easy penetration of materials. The surface can be treated with rust prevention such as galvanizing and nickel plating to enhance durability. The threads are divided into coarse and fine threads according to the usage scenario. The coarse thread has a larger pitch and is suitable for quick screwing in, while the fine thread is more suitable for thin-walled parts or occasions subjected to impact and vibration.

Size specifications: The diameter range is from 1.6 millimeters to 12 millimeters, and the length ranges from 4 millimeters to over 100 millimeters, which can meet the fastening requirements of materials with different thicknesses.

• Working principle

Use a screwdriver to fit into the straight groove of the screw head, and use the torque generated by rotating the screwdriver to screw the screw into or out of the connected object, achieving the function of fastening or disassembling. When operating, it is necessary to keep the screwdriver perpendicular to the screw slot, otherwise it may cause problems such as slipping and twisting the slot.

• Application scenarios

Daily life: commonly used in furniture assembly to connect wooden boards; Electronic products such as radios and small household appliances often use slotted screws to fix components such as casings and internal circuit boards due to their compact space and low requirements for screw size accuracy.

In the industrial field: In some light industrial product production lines that do not require high installation speed and accuracy, such as toy manufacturing and simple plastic product assembly, slotted screws are widely used due to their low cost and convenient installation.

• Advantages and disadvantages

Advantages: Simple structure, mature manufacturing process, low production cost; It can be operated with a regular flathead screwdriver, which has strong versatility and is convenient for daily maintenance and repair; The design of the slotted screw slot allows the screw head to be made thinner, making it suitable for installation environments with limited space height.

Disadvantages: The single slot has a small force bearing area, making it easy for the screwdriver to slip when tightening or disassembling, resulting in slot wear and affecting subsequent operations; The limited torque that can be applied makes it difficult to meet the high requirements for fastening force in situations; Compared to other types such as Phillips screws, Phillips screws are more prone to loosening under prolonged vibration or stress.
