One-Slot Round Head Screw

Product introduction

The slotted round head screw is a classic fastener, and its hemispherical round head and slotted design are its distinctive features. The round head design is beautiful, can provide good surface contact, and reduce pressure loss on the surface of the workpiece. It mainly uses an ordinary screwdriver or a flat-head screwdriver for loading and unloading. It is easy to operate and low in cost. This kind of screw is suitable for a variety of occasions that do not require high tightening torque. It is commonly used in furniture assembly, electrical casings, light machinery, and daily necessities. Although its applicability is limited in situations where high torque and anti-tampering are required, slotted round head screws are still a basic and important connection solution in many industries due to their economy, versatility and ease of production.

 

Product Features

1. Easy to install and disassemble, low cost: Only an ordinary flat-blade screwdriver is needed to complete installation and disassembly. The tool is widely available and low-cost, making it easy for daily maintenance.

2. Round head design, surface-friendly: The screw head is hemispherical and has a large contact area with the workpiece, which can effectively reduce indentation and damage to the surface of the connecting piece, and the appearance is more rounded and beautiful.

3. Wide applicability: As a basic fastener, it is widely used in furniture, home appliance casings, light mechanical equipment, toys and many daily necessities. It is a common general-purpose screw.

4. Convenient for counterbore design: Its round head shape is very suitable for use with counterbore holes, allowing the screw head to sink under the surface of the workpiece to achieve a smooth installation effect.

5. Limitations: Easy to slip: When the slot is subjected to a large torque, the screwdriver easily slips out of the slot, causing damage to the slot (commonly known as "twisting"). Low torque capacity: Not suitable for applications requiring high-strength fastening and high torque. Low degree of automation: Compared with cross recess, hexagon socket, etc., the positioning and driving efficiency in automated assembly is low.

 

Product application

1. Furniture assembly and woodworking fields: Commonly used in the connection, splicing and fixing of wooden furniture, such as chairs, tables, cabinet door hinges, etc. Its round head can effectively avoid excessive pressure damage to the wood surface.

2. Household appliances and electronic equipment: It is widely used to fix the shells of electrical equipment, such as old radios, power adapters, small switch boxes, etc. It is often used for sheet metal parts or plastic shells that do not require high tightening torque.

3. Light mechanical equipment and instruments: It is suitable for the installation of some mechanical panels and protective covers with light loads, as well as the internal structure fixation of instruments and meters.

4. Daily necessities and repairs: Commonly found in daily necessities such as door and window hardware, toys, bags, glasses, etc. Due to its popularity as a tool, it is also very suitable for home DIY repairs and replacements.

 

FAQ

Q: What are the biggest advantages and disadvantages of slotted screws?

A: The biggest advantage is that the tools are widely available and the cost is low. The biggest disadvantage is that when a large torque is applied, the screwdriver easily slips out of the slot, causing damage to the slot and a low transmitted torque value.

 

Q: Why do many new products no longer use slots but use cross slots?

A: Mainly because the cross recess has better centering, the screwdriver is not easy to slip out, can withstand higher tightening torque, is more suitable for manual and automated assembly, and improves efficiency and reliability.

 

Q: What should I do if the screw head is screwed or slipped?

A: You can try the following method: place a piece of rubber or coarse cloth in the groove to increase the friction before tightening. Use a small amount of strong glue to stick the screwdriver in the slot, and unscrew it after it solidifies. Use a special tool such as a counter-wire extractor or impact screwdriver. In the worst case scenario, the screw head can be drilled out with a small drill bit.

 

Q: In what situations is it not suitable to use slotted screws?

A: In situations that require frequent disassembly and assembly, high vibration environments, precise requirements for tightening torque, high anti-disassembly security, or automated mass production, it is not recommended to use slotted screws. Instead, hexagonal, cross-recessed or other more reliable screws should be preferred.
