Frequently Asked Questions

Define of fasteners?
Fasteners are tools that hold two pieces together in a non-permanent joint. For example, using a deck screw to attach a deck board to a ledger board creates a joint. Because in theory, these two pieces can be separated, they are considered non-permanent. Unless you are welding, you will most likely be creating non-permanent joints using your drill or screwdriver.

What is the difference between the grades in Metric and Imperial bolts?

The main difference between the grades in metric and imperial bolts is how each is measured. Metric bolt heads are measured in millimeters while Imperial (or standard) are measured in inches or fractions of inches.

Which fasteners meet my ASTM code?

The most common ASTM codes referenced for fasteners are ASTM A36, ASTM A47, ASTM A48, ASTM A153, ASTM A193, ASTM A194, ASTM A307, ASTM A320, ASTM A325, ASTM A354 and ASTM A449. Mudge is able to supply fasteners to meet these ASTM specifications and others. If you’d like to download individual ASTM standards documents,

What is the difference between a bolt and a screw?

Traditionally, the difference between a bolt and a screw has been defined as a screw is threaded to the head whereas a bolt has a plain shank. However, using this definition now could cause problems if this assumption is made when specifying a fastener. The definition used by the Industrial Fastener Institute (IFI) is that screws are used with tapped holes, and bolts are used with nuts.

Obviously, a standard ‘bolt’ can be used in a tapped hole or with a nut. The IFI maintains that since this type of fastener is normally used with a nut, then it is a bolt. Although certain short length bolts are threaded to the head, they are still bolts if the main usage is with nuts. Screws are fastener products such as wood screws, lag screws and the various types of tapping screws. The IFI terminology and definition has been adopted by ASME and ANSI.

What are the marks shown on the head of a bolt?

Fastener standards specify two types of marks to be on the head of a bolt. The manufacturer’s mark is a symbol identifying the manufacturer (or importer). This is the organization that accepts the responsibility for ensuring that the fastener meets specified requirements. The grade mark is a standardized mark that identifies the material properties that the fastener meets. For example, 307A on a bolt head indicates that the fastener properties conform to the ASTM A307 Grade A standard. The bolt head shown at the side indicates that it is of property class 8.8 and remain is the manufacturer’s mark.

Both marks are usually located on the top of the bolt head, and most standards indicate that the marks can be raised or depressed. Raised marks are usually preferred by manufacturers because these can only be added during the forging process whereas depressed marks can subsequently be added (possibly with illegitimate marks).

Whats common surface treatment methods for fastener?

1. Zinc plating
2. Surface phosphating
3. Blackening (oxidation)
4. Cadmium plating
5. Chromium plating
6. Silver and nickel plating on the surface
7. Galvanizing (hot dip galvanizing and zinc infiltration)
8. Fluorocarbon coated,Xylan Fluoropolymer Coated
9 PTFE
