DIN787 Bolts And Screws For T-slots
DIN787 Bolts And Screws For T-slots
T Bolts, also known as T-Slot Bolts, are commonly used in machine tools and industrial applications as a securing solution for fixtures, jigs, and assemblies. DIN787 is a European standard for T Bolts, outlining specific dimensions and material specifications. Designed with a unique T-shaped head, T Bolts offer versatility in positioning options and a secure hold in T-Slot extrusions. Their thread length varies depending on the required grip length and material being secured.

T Bolt DIN787: A Guide to Choosing the Right T Bolt for Your Application
T bolts are a crucial component in a variety of industrial and mechanical applications. These bolts are designed to secure two objects together, often used in situations where regular bolts are not sufficient due to the shape or thickness of the materials being fastened.
DIN 787 is a standard that outlines the specifications for T bolts. These bolts are known for their unique T-shaped head that allows for a greater surface area of contact and provides increased holding power when tightened.
When choosing a T bolt DIN 787 for your application, there are several factors to consider, including:
1. Material
T bolts are available in various materials, including stainless steel, carbon steel, and brass. The material you choose will depend on your specific application requirements, such as strength, corrosion resistance, and temperature resistance.
2. Thread
T bolts come with either a metric or imperial thread. It is essential to choose the correct thread size to ensure a secure fit.
3. Size and Length
T bolts are available in various sizes and lengths, and it is crucial to select the right size for your application. Consider the thickness of the materials being fastened, as well as the amount of clamping force required.
4. Coating
To improve corrosion resistance and provide additional protection against environmental factors, T bolts can be coated with materials such as zinc, nickel, and chrome. The coating you choose will depend on your application requirements and the conditions in which the bolt will be used.
5. Head Type
T bolts come with different head types, including hexagon, square, and round heads. The head type you choose will depend on the application requirements, such as the size of the wrench needed to tighten the bolt.
In summary, selecting the right T bolt DIN 787 for your application requires careful consideration of various factors, including material, thread, size and length, coating, and head type. By taking these factors into account, you can ensure that your T bolt will provide secure and reliable fastening, helping to ensure the safety and efficiency of your application.

Common Fastener Materials
Fasteners are fabricated from a variety of materials. These options include metals and polymers. Stainless steel offers strength and corrosion resistance. While polymer options have less strength than stainless, they are a good choice for resisting chemicals. The most common materials are:
- Stainless steel
- Alloy steel
- Low carbon steel
- Medium carbon steel
- Titanium
- Polymers, such as nylon
Finish Options
The use of heat treatments and application of various finishes, also known as “plating,” affects the look and performance of fasteners. Finishes provide material stability and protect the fasteners from corrosion and rust. Below are some common heat treatment and finish benefits:
- Zinc coating – Most common, low cost, resists corrosion and rust
- Galvanized – Superior corrosion protection, anti-seize, higher upfront investment
- Stainless – Great for humid environments, strong, ideal for electrical or mechanical uses
- Black – Adds color, provides better grip, deflects light

FAQ
Q: Do bolts have different threads?
A:Bolts with coarse threads have a larger pitch (fewer threads per axial distance) compared to fine threads. A coarse threaded bolt is specified for most applications unless there is an overriding reason to use a fine threaded bolt (e.g. thorough thread adjustment is crucial for the application).
Q: What is difference between screw & bolt?
A: A bolt is meant to be used with a nut, and it is tightened by torquing the nut. A screw is designed to be used in either a preformed or threaded hole, or it is capable of forming its own threaded hole. A screw is designed to be tightened by torquing the head.
Q: Are bolts stronger than screws?
A: Yes, bolts provide greater holding strength than screws. This is partly due to the presence of the washer, which spreads out the load over a larger surface area. Because bolts offer increased strength, they work well for heavy-duty, load-bearing applications.
Q: Does every bolt need a nut?
A: Sometimes two bolts are used to prevent a beam from swiveling. Tap Bolt: This kind of bolt is completely threaded. It is used in a threaded or tapped hole and does not need a nut. A bolt is a type of fastener that often needs a nut that is tightened on the end and helps fasten several materials together.
Q: Why use screws instead of bolts?
A: Uses Screws and bolts are both used to fasten objects together, but bolts are for more heavy-duty projects. While bolts are the better choice for construction, building, or anchoring items, screws are best for home repairs, hanging objects, and DIY builds.
Q: What is the weakest part of a bolt?
A: The weakest part of any fastener is the deepest region of its threads (the root), and although the thread diameters in each case are the same the cold formed root diameter of a rolled thread may increase in strength.
Q: Are stainless steel bolts weaker than steel?
A: In fact, due to their low carbon content, many stainless steel alloys cannot be hardened through heat treatment. Therefore, when compared to regular steel, the stainless alloys used in bolts are slightly stronger than an un-hardened (grade 2) steel but significantly weaker than hardened steel fasteners.
Q: Can bolts be too long?
A: If the bolt is too long, its point may come into contact with the anchor’s expansion cone before the head of the bolt reaches the material to be fastened.
Q: Why are bolts so strong?
A: When a bolt is tightened the shank sustains a direct stress, due to the elongation strain, together with a torsional stress, due to the torque acting on the threads.
Q: Why are bolts better than rivets?
A: Bolts have largely replaced rivets due to their lower installation cost, ease of installation and maintenance. The two types of bolts commonly used in steel construction include high strength structural steel, and A307 bolts (common bolts).
Q: Do bolts weaken over time?
A: Nuts and bolts can loosen over time even if they are only subjected to translatory forces due to several factors: Vibration: Translatory forces can result in vibration in mechanical systems, especially in equipment or machinery that operates at high speeds or experiences frequent changes in direction or load.
Q: Do bolts need threaded holes?
A: Because metal is a stronger material, the screws thread cannot cut into it, so they must be inserted into a tapped or threaded hole. They both give extra grip to ensure that the screw stays in place. Both processes are used for a bolt, screw, or nut.
Q: Do bolts need washers?
A: Washers are used to distribute the load of a threaded fastener, such as a bolt or nut. Before a screw or bolt is driven into a surface, a washer may be placed in order to prevent looseness and provide protection. This also prevents the bolt head and nut from damaging the surfaces of the two fastened parts.
Q: Why does bolt have rubber?
A: Rubber spacers for bolts are especially useful for securing fasteners in high-vibration applications because the rubber will absorb the vibration to keep the fastener from loosening unexpectedly.
