Stainless A4-70 G316 Hex Coach Screws DIN 571 M10*50

Description

Product Introduction
This A4-70 grade 316 stainless steel external hexagonal carriage self tapping screw produced by VANGUARD INDUSTRIAL complies with DIN 571 standard and has a specification of M10 * 50. It is a high-performance anti-corrosion self tapping fastener:
Material performance: Made of G316 austenitic stainless steel, with the addition of molybdenum element, its corrosion resistance in chloride environments, marine conditions, and weak acid and alkali environments is much better than that of ordinary 304 stainless steel. The minimum tensile strength corresponding to A4-70 performance level can reach 700MPa, and its strength performance is equivalent to 8.8 grade carbon steel screws, with excellent load-bearing and fatigue resistance.
Structural features: Adopting the classic design of half tooth external hexagonal head and pointed tail self tapping teeth, it does not require the use of nuts and can be directly screwed into wooden, low-density metal or other substrates through its own threads to complete fastening. The hexagonal head can be tightened with a wrench to apply greater locking force and avoid slipping.
It is widely used in outdoor wooden structure construction, ship assembly, chemical anti-corrosion equipment, outdoor curtain wall fixation, landscape engineering and other scenarios that require high requirements for rust prevention and anti-corrosion.
🛠️ Usage
Preparation in advance
Confirm that the substrate to be tightened is compatible with this M10 self tapping screw, prepare a socket wrench or torque wrench of the corresponding specification in advance, check the screw thread for defects such as burrs and deformation, and when working on hard wood or thick metal substrates, it is recommended to drill a suitable guide bottom hole in advance to avoid substrate cracking or screw breakage when screwing in.
Installation operation
Align the tip and tail of the screw with the pre positioned installation point, and use a wrench to apply torque at a constant speed to screw the screw into the substrate. Keep the screw perpendicular to the surface of the substrate throughout the entire process until the hexagonal head fully adheres to the surface of the workpiece, completing the fastening.
Precautions
316 stainless steel material has high toughness. It is recommended to control the speed during high-speed screwing to avoid thread locking and biting; This self tapping screw is suitable for heavy-duty anti-corrosion scenarios and is not recommended for use on ultra-thin boards to prevent loosening due to insufficient connection strength
