Fastener 4 – August 2022

What is Bondsert® and commonly asked questions:

Q: What is Bondsert®?

A: Bondsert® is an internally and externally threaded fastener with Loctite™ 204 adhesive applied to the external threads. They are interchangeable with E-Z Lok® thread inserts for metal.

Q: What are the applications for Bondsert®?

A: Bondsert® provides a stronger fastener assembly in soft materials such as aluminum, magnesium and even cast iron. They can be used for repairing stripped threads, and for use in creating stronger threads in original equipment. They are available in both thin wall and heavy wall styles, and in both C12L14 carbon steel and 303 stainless steel.

Q: How is Bondsert® installed?

A: Bondsert® external threads are manufactured with standard size and pitch to permit the use of standard drills and taps. They can be installed with a screwdriver, bolt/jam nut or power drive tools.

Q: Is Bondsert® a better solution when compared to wire thread inserts or key-locking inserts?

A: Not really. Wire thread inserts are a lighter and less expensive solution. Key-locking inserts are an overall heavyweight solution. All have styles which are vibration resistant. With Bondsert®, within minutes of installation the Loctite™ 204 adhesive begins to set and within 5 minutes is fastener ready and will not back out. A key advantage of Bondsert® is that the Loctite™ 204 adhesive seals against liquids and gases up to 6,000 psi when fully cured after 72 hours.

Fastener 4 – July 2022 Featuring Loksert

Q1: How do Loksert inserts work?
A: Once installed, the keys are driven into the parent material providing a positive mechanical lock against rotation.

Q2: How many keys are there in Loksert inserts?
A: For internal diameters up to 1/4″ & M6, there are two keys per insert. Larger sizes have 4 keys.
Q3: Are self-locking inserts available?
A: Yes, Loksert inserts with an internal locking feature are available. The self-locking feature prevents the mating fastener from backing out of the hole in vibration prone assemblies.

Q1: Do Loksert inserts come in different lengths?
A: No, there is a single standard length for all Loksert inserts. That data can be found in the manufacturer’s literature or on their website.

Helical Wire Thread Inserts

More commonly asked questions about problem-solving, insert materials, and installation.

Q: How to prevent thread galling?
A: This is a common problem when using screw-locking helical coil inserts and occurs when the mating fastener passes through the locking coils and binds. The result is the insert threading out of the hole when the bolt is removed, or the insert is threaded too deep in the tapped hole.
The most common cause of galling is the use of 303 series stainless steel bolts. Helical wire thread inserts are made of cold-rolled 304 stainless steel wire, work-hardened to a tensile strength greater than 200,000 psi and a hardness of Rc 43-50. To minimize galling it is recommended to use heat-treated screws with a hardness of Rc36-43.
In applications where stainless steel screws are mandated, or when using heat-treated unplated bolts it is recommended to use an anti-seize compound such as moly-disulphide to minimize galling. Specifying inserts with dry-film lubricant plating is another option. Lastly, Nitronic 60® could also be specified.

Q: What materials are helical wire thread inserts produced from?
A:
• 304 Stainless Steel (standard), specification AS7245. Used for most general-purpose applications up to 425℃ (800℉).
• Inconel X-750, specification AS7246. This is a nickel alloy for resistance to chemical corrosion and oxidation. Also used for high temperature applications up to 750℃ (1300℉).
• Phosphor Bronze, specification AS7247. Used for electrical bonding joints, copper parts requiring high resistance to some electrolytic couples, and saltwater applications up to 300℃ (570℉).
• Nitronic 60®, alloy number UNS S21800. Specifically designed to minimize galling when used with stainless steel screws with excellent high temperature performance.

Q: Should tapped holes be countersunk prior to insert installation?
A: To facilitate insert installation and prevent a feather edge or burr build up on the tapped hole, countersinking on the drilled hole at 120° included angle is recommended and the average depth of the countersink is ½ pitch.

Q: At what depth should the insert be seated?
A: It is recommended that the inserts be installed ¾ to 1.5 pitches below the top surface of the tapped hole.

Fastener 4 : E-Z Chamfer®

Q1: What is E-Z Chamfer?
A: E-Z Chamfer is a cylindrical tool with 5 cutting blades made of M2-HHS steel designed to create a perfect chamfer on many materials. The tool has a ¼” hex shank so it works easily with battery operating drills. When used on metal, threads and burrs are sheared off creating the chamfer for starting a nut or threaded die.

Q2: On what materials can E-Z Chamfer be used?
A: The tool can be used on ferrous and non-Ferrous metals, including hardened steels, timber, fiberglass, and plastics. As for steel, E-Z Chamfer can be used on the following materials:

Mild Steel – U.S Grade 2, Metric Grade 4.8
Hard Steel – U.S Grade 5, Metric Grade 8.8
Very Hard Steel – U.S. Grade 8, Metric Grade 10.9
Stainless Steel – 300 Series
Super Hard Steel – U.S. Grade ASTM-A574, Metric Grade 12.9

Q3: On what diameters does E-Z Chamfer work?
A: 5/16 – 7/8”, M8 – M22

Q4: What do you need to be mindful of when using E-Z Chamfer?
A: Use at low speed – Maximum 800RPM. Guidelines:

Start E-Z Chamfer square to the workpiece. A circular motion may improve performance on large diameter workpieces.
E-Z Chamfer works by shearing a small amount of material every revolution. Slow drill speed with medium pressure will yield the best results in most materials. Hard materials will require high feed pressure. In most applications it is only necessary to chamfer the first 1 to 3 threads. Wear eye protection.
