1022A Carbon Steel Flat Head Phillips Self-Drilling Screws
Product Overview
1022A Carbon Steel Flat Head Cross Recess Self-Drilling Screws are manufactured from 1022A carbon steel. Designed with cross drive recess and flat head self-drilling tip, they are suitable for connections of thin metal sheets, light steel components, sheet metal parts, equipment housings and other applications. The self-drilling tip facilitates penetration into substrates, while the threads provide consistent clamping force. The flat head minimizes surface protrusion after installation, improving assembly efficiency, connection stability and the neat appearance of finished products.
Core Selling Points
- 1022A carbon steel material: Suitable for conventional industrial fastening requirements, with compatible sizes and surface treatments available according to the application.
- Phillips drive design: Compatible with commonly used Phillips bits, making on-site installation more convenient.
- Self-drilling point: Suitable for fastening metal sheets and related accessories, supporting continuous drilling and fastening operations.
- Flat head profile: Helps the fastener sit closer to the installation surface and reduces exposed height after tightening.
- Bulk purchasing support: Thread specifications, surface treatment, packaging, and order quantities can be discussed according to purchasing requirements.
Applications
This product is suitable for metal roofing and wall accessories, light-gauge steel structural components, ventilation duct fittings, metal frames, equipment housings, sheet-metal parts, and other assembly applications that require self-drilling fastening. During selection, the appropriate thread size and length should be determined according to the thickness and hardness of the base material, the installation tool, and the required connection strength.

Structure and Use Instructions
The flat head Phillips self-drilling screw consists of a head, Phillips drive recess, threaded shank, and self-drilling point. During installation, align the screw vertically with the connection position, select a matching Phillips bit, and apply steady pressure so that the drilling point enters the base material before the threads complete the fastening process.
For base materials with different thicknesses or hardness levels, the screw size, tool speed, and torque should be selected according to the actual installation conditions. Excessive tightening should be avoided to prevent damage to the drive recess, thread failure, or deformation of the connected surface.
The flat head design is suitable for installation areas that require a relatively smooth appearance. For humid, outdoor, or corrosive environments, an appropriate surface treatment should be selected according to the specific operating conditions.
Bulk Purchasing and Customization
For hardware distributors, engineering contractors, metal component manufacturers, and branded procurement teams, the thread size, length, surface treatment, packaging labels, and outer carton requirements can be discussed according to the target market and application. The minimum order quantity, delivery schedule, and transportation method can be confirmed based on the specific order.
Frequently Asked Questions
Can this self-drilling screw be used with all metal materials?
