316 Stainless Steel Cotter Pins
AISI 316 Split Pin Manufacturer in India

316 stainless steel cotter pins are fasteners which can used to hold two or more components securely in different mechanical applications. SS 316 Cotter pins in the most general sense are split pins or safety pins which are passed through holes in a shaft or some other part and bent to lock them in position. Cotter pins made from 316 stainless steel serve several unique functions, most importantly in situations where corrosion is a massive issue. Prashaant Steel and Alloys is reliable supplier of 316 SS cotter pin as per DIN 94 standard. The company conduct wide range of testing procedure to ensure quality of this product.
AISI 316 Large Cotter Pin are usually a wire or rod piece of metal, which may be bent half lengthwise into two forked legs. As for when this is put through a hole in a fastener or shaft the legs of the pin are curved over to ensure it does not come off easily. Prashaant Steel offers AISI 316 split locking pins which are tailored to meet various industrial needs. PSA is already supplying Alloy 316 cotter pins in UAE, Italy, Kenya and Indonesia.
Standard Cotter Pins: These are the most usual varieties with rounded head/and or divided legs.
Tapered Cotter Pins: All of them are a little more conically shaped than round ones, which provides better fixation of parts in some cases.
Enhanced Corrosion Resistance: The enhanced capability of 316 stainless steel against chloride environment, acids and alkaline substances tends to provide longer lasting of cotter pins used in such conditions.
Strength and Durability: The SS 316 Split Pins is capable of withstanding the mechanical loads that tend to be applied to these pins all along without seemingly cracking or deforming in the process.
Non-Toxic and Safe: These are non-galvanic, which makes it ideal for use in the industries of food processing and manufacturing of foods and beverages, and in pharmaceutical industries.
The SS 316 cotter pin is then hammered to fit into a small slot around this shaft or bolt. The legs are then arranged in a way that folds over the shaft to hold this pin which prevents the components from coming off again.
