Product Introduction
Stainless steel cap screw is a roll mounted nail made of 304/316 stainless steel as the base material, which does not require additional coating on the surface (with anti rust properties). It is matched with a large umbrella shaped nail cap with a diameter of 8.8mm-9.2mm, a nail body diameter of 2.96mm, a length of 3/4 "-1-3/4", and can be divided into light body, ring pattern and other types. It is suitable for CN series nail guns and is a special fastening accessory for high corrosion environments.
Product Advantage
1. Ultimate corrosion resistance: 304 stainless steel can withstand weak acid and alkali, humid salt spray environments, while 316 stainless steel is more suitable for high corrosion scenarios such as marine and chemical industries, with no risk of coating peeling and a rust proof life far exceeding hot-dip galvanized nails.
2. More stable material: The stainless steel substrate has uniform hardness and good toughness, and the nail body is not easily bent or broken. The risk of splashing during shooting is low, and it is suitable for difficult to penetrate materials such as hard wood and thin metal.
3. Neat appearance: The surface has a matte metallic texture, without oxidation or discoloration of the galvanized layer, suitable for scenarios with high external cleanliness requirements (such as food packaging and medical equipment packaging).
4. Tightness upgrade: The combination of large nail cap and ring pattern nail body increases the biting force by more than 20% compared to ordinary stainless steel nails, avoiding workpiece loosening, and the large nail cap can reduce material cracking.
Technical Parameters

Product Uses
1. High corrosion environment: Marine engineering (stack roads, guardrails), equipment fixation in chemical workshops, outdoor component splicing in coastal buildings.
2.Clean/special fields: food grade wooden pallets, medical equipment packaging wooden boxes, pharmaceutical workshop wooden tool fixation.
3.High end scenarios: assembly of high-end outdoor furniture, fastening of wooden components for yacht interiors, and packaging of precision instruments in wooden boxes.
Tool preparation
1. Confirm that the model of the nail rolling gun matches the specifications (diameter/length) of the nails (priority should be given to selecting a specialized nail rolling gun that is compatible with stainless steel nails to avoid rapid wear of ordinary gun heads);
2. Check the stability of the gun body air pressure (usually 0.5-0.8MPa, stainless steel nails have high hardness, and the air pressure should not be too high to prevent gun jamming).
Loading coil nails
1. Open the magazine of the coil nail gun and neatly place the stainless steel coil nails (note that the nail head is facing the muzzle, and the coil nails need to be completely embedded in the magazine guide rail);
2. Close the magazine and lock it, gently pull the nozzle to confirm that the nail body is not stuck.
Homework operation
1. Align the workpiece and keep the gun body perpendicular to the working surface (stainless steel nails have high hardness and tilting can easily cause the nail body to bend or the nail cap to shift);
2. Press the nozzle trigger switch to fix one nail in a single shot. During continuous operation, the gun body should be kept stable to avoid repeatedly hitting the same position;
3. If encountering hard materials such as hardwood or thin metal, adjust the air pressure appropriately (recommended 0.6-0.7MPa) to avoid nail breakage.
Closing and maintenance
1. After homework, clean the remaining nails in the gun, turn off the air source, and wipe the gun nozzle with a special cleaning agent (to avoid stainless steel debris residue and wear on the gun head);
2. Unused coil nails should be stored in a sealed manner (avoiding long-term exposure to high humidity environments. Although stainless steel is rust resistant, humidity may affect the toughness of the coil nails).
