Description
DIN 7985 cross pan head screw is a kind of mechanical screw. Its head is a semicircular fastener with cross groove and external thread, also known as cross groove pan head screw.
The cross pan head screw is mainly used for the fastening connection between a part with an internal thread hole and a part with a through-hole without nut matching. This connection form is called screw connection and also belongs to detachable connection.
DIN 7985 Product Details
DIN 7985 The groove type of the head of cross pan head screw can be divided into H type and Z type
The performance grade of carbon steel cross pan head screw is grade 4.8 and grade 8.8. The performance grade of carbon steel is divided by tensile strength.
Generally, carbon content in carbon steel is used to distinguish low carbon steel, medium carbon steel, high carbon steel and alloy steel. Low carbon steel C ≤ 0.25%, generally used for screws and other products without hardness requirements. Medium carbon steel 0.25% ≤ C ≤ 0.45%, mainly used for grade 8.8 screws and bolts.
The surface treatment of carbon steel cross pan head screw needs to be carried out. Electroplating is commonly used, including zinc plating, copper, nickel, chromium, copper nickel alloy, etc. The surface of din7985 cross pan head screw is galvanized.
The carbon steel cross pan head screws of screw Street are grade 4.8, which are also common screws. There are two types of plating blue white zinc and color zinc.
The cross pan head screw is generally used in the situation where greater stress is required. The larger pan head is more conducive to the fixation of the product to be fastened. At the same time, because the head is larger, it is more convenient to assemble. It is often used in the superposition and fixation of sheet metal parts. The plate head is large and the contact area between the fixed object and the plate head is large, which increases the axial tightness and is convenient for CNC punching of sheet metal parts.
The cross pan head screw is widely used in the fastening of mechanical case, case or cover or parts of household appliances.

Frequently Asked Questions
What Does M2.5, M3, M3.5, M4, M5 Mean?
How Do I Cut a Machine Screw?
Cutting a small machine screw (up to standard size #10 or metric size M5 (5mm)
Use a pair of multipurpose wire strippers or electricians pliers that feature M2.5, M3, M3.5, M4, M5 threaded holes. These holes are designed for cutting bolts without damaging the thread. Open the jaws and thread the machine screw into the correct size hole to the distance required. Squeeze the tool handles closed and the screw will be cut at the point where the two halves of the jaws come together. You will have a clean cut without any thread damage.
Cutting a large machine screw (larger than size #10 or metric size M5 (5mm)
This is best done using a hacksaw. Thread the nut on the screw until it reaches the desired point on the head side of the cutting line. Place the screw in a vice or clamp to keep it secure when cutting and cut the screw as straight as you can. When you unthread the nut it will repair and realign any threads that may have been damaged by the saw blade.
