Q. Things to consider while ordering fasteners?

Answer: The following must be considered while buying fasteners: -
Quality: - It is the ability to not only satisfy customer requirements but to exceed them. A typical fastener must be in a position to adhere to all customer specifications, requirements, drawings and needs.
Timely Delivery: - One must place an order to companies who can provide consignment/material within specified. Such that there are no delays in your projects.
After sales: - You need a team that supports you even after your purchase.
At pioneer we have a dedicated technical and sales team for the same.

Q. What are Defects/ Failures that may occur in fasteners?

Answer: The following are Defects/Failures that occur in fasteners: -
• Dimension problems: - Most of the fasteners manufactured do not comply to dimensional standards. Slight dimensional variations can cause major failure in your projects.
• Cracks: - Using poor quality material, lack of quenching knowledge, poor forging, problem in die can cause cracks. Sometimes these cracks may be so small that they may not be visible to human eye.
• Functionality Tests: - Hardness, Tensile strength, toughness, Ductility, pitch are some of basic factors that must be kept in mind while manufacturing fasteners.

Q. How Is fastener market in India?

Answer: The Indian industrial fasteners market is expected to reach a value of INR 460 Bn by 2023 expanding at a CAGR of ~9.6% from 2018.
With help from the Indian government’s ‘Make in India’ initiative, the Indian manufacturing sector is expected to generate huge demand for the industrial fasteners market.
Thus there is a huge scope for the Indian fastener market. Since India is a developing country there is a lot of demand in sectors like railways, construction, infrastructure mining and many more – “Research & Markets”

Q. What are different types of fastener finish. What is importance of each finish?

Answer: The following are the five most popular types of coatings for fasteners that may meet your requirements:
Clear Zinc: This is one of the most popular fastener coatings available in the market. Inexpensiveness is one of the main reasons for their immense popularity. The clear zinc coated fasteners can withstand oxidative damage. Thus, the clear zinc coatings are recommended for conditions, where they are exposed to high humidity, and stand a high risk of rusting.
Yellow Zinc: The yellow zinc coating is applied electrically to the fasteners. These coatings are ideal for conditions where the fasteners may come in contact with water or other liquids. The yellow zinc coating is also ideal for humid conditions. These coatings need to be applied precisely to inhibit corrosion.
Gray Phosphate: This is another important fastener coating which is designed to improve the lifespan of fasteners. However, this type of coating is not recommended for conditions where there is a high risk of corrosion. For example: gray phosphate coated fasteners are not ideal to use in marine applications. This means they should only be used in dry settings such as vehicles or interiors of buildings, etc.
Hot Dip Galvanized: Also, referred to as HD, this coating is applied on steel to protect it from corrosion. The hot dip galvanized fasteners are coated with zinc. These fasteners are generally considered for outdoor applications where they will be exposed to extreme weather conditions such as snow, heat, and rain. The HD fasteners are also ideal for coastal areas where the salt content is higher.
Electro Galvanized (EG): These fasteners have a thin layer of zinc coating which offers frugal corrosion protection. The EG fasteners are used in areas where less corrosion protection is needed such as kitchens, bathrooms, or other areas that are susceptible to humidity or moisture. Most fasteners used in roofing are electro galvanized and are replaced before the fastener starts wearing.
There are many other coatings but only few popular are discussed here.

Q. What elements are important in fasteners?

Answer: A. The following are very important elements that must be considered while buying fasteners:

Thread A thread can make or break the quality of fasteners. Poor quality thread is a major problem in fastening industry. If these factors are not taken into account either of the following happen: -
Go – No go problem.
Problems in pitch, major and minor dia.
At Pioneer we have a research team that takes into account each factor like pcd, pitch, major dia and minor dia. To ensure that you get the perfect fastener that caters to your requirements.
Across Flat: -The width across flats of hexagon or square heads of fasteners is the distance measured perpendicular to the fastener axis across the flats of the fastener.
Across flat must be strictly as per the specifications and standards
Raw- material – Raw material if not selected in an appropriate manner can lead to cracks, lower tensile and yield strength. Most of the suppliers use poor quality raw material to save costs. They may not have proper knowledge about metallurgy due to which proper tensile strength, toughness and hardness may not be achieved.
