They are fully threaded and conform to DIN 933 standards. Can be used with many Nut types and washers. APPLICATION: For fastening together numerous types of material or to be fastened in to pre-tapped holes. Widely used in many engineering applications. Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrates surface integrity as it is formed. The zinc oxide, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers.

FAQs
What does 'high tensile' mean for these screws?
'High tensile' refers to the steel's increased strength, meaning it can withstand a significantly larger amount of pulling or shearing force before deforming or breaking compared to standard steel screws. This makes them suitable for heavy-duty applications.
Can these M10 x 70 set screws be used outdoors?
Yes, the zinc-plated finish provides good corrosion resistance, making them suitable for many outdoor applications. However, in extremely corrosive environments (e.g., marine or industrial chemical exposure), additional protection or different materials might be required for optimal lifespan.
What size wrench or socket do I need for an M10 hex head set screw?
For an M10 hex head set screw, you will typically need a 17mm wrench or socket.
What is the recommended torque specification for these screws?
Info needed: [Specific torque values depend heavily on the material being fastened, the joint type, and the exact application. Always consult relevant engineering standards (e.g., ISO, DIN) or your project's specific torque chart for M10 high-tensile fasteners to ensure proper and safe installation.]
What is the difference between a 'set screw' and a regular 'bolt' in this context?
While the term 'set screw' can sometimes refer to headless fasteners, in this context (Forgefix High Tensile Set Screw - M10 x 70), it refers to a hex head fastener that is *fully threaded* along its entire shaft, unlike many standard bolts that have a partially unthreaded shank. This full threading maximizes thread engagement.
Are these screws reusable?
Generally, high tensile fasteners can be reused if they have not been subjected to excessive stress, deformation, or significant corrosion. Always inspect them thoroughly for any signs of damage (e.g., stretched threads, bent shaft) before reinstallation, especially in critical applications.
Troubleshooting
Set screw won't thread or tightens with difficulty.
Check the internal thread of the mating component for damage or debris. Ensure you are using the correct M10 thread. Apply a thread lubricant if necessary.
Set screw feels loose after tightening, or joint moves.
Verify that the correct torque specification was applied. Check for deformation in the materials being joined or if the screw length is too short for full engagement. Ensure compatible nut and washer (if used) are of appropriate grade.
Corrosion appears prematurely on the set screw.
While zinc-plated, extreme environments (e.g., highly saline, acidic) can accelerate corrosion. Ensure proper environmental sealing if possible, or consider additional protective coatings for such conditions.
Set screw head strips or rounds off during tightening.
Ensure you are using the correct size and type of wrench/socket that fits snugly. Avoid using worn tools. Lower the torque setting and tighten more gradually.
Pros and Cons
Pros
Exceptional Strength: High tensile steel construction allows for secure fastening in high-stress applications.
Corrosion Resistance: Zinc plating enhances durability and protects against rust and environmental wear.
Wide Applicability: Suitable for critical joints in diverse fields like machinery and structural work.
Cons
Tooling Requirement: Requires specific M10 wrenches or sockets for proper installation and removal.
Torque Sensitivity: Over-tightening can strip threads or damage components, necessitating a torque wrench for critical applications.
Not for Shear-Only Loads: While strong, fully threaded bolts are generally less ideal for pure shear applications compared to bolts with unthreaded shanks that fill the hole perfectly.
Setup, Compatibility & Care Instructions
Setup
Preparation: Ensure the components to be joined are clean and free of debris. If tapping a new hole, use an M10 tap to create compatible internal threads.
Tool Selection: Use an appropriately sized M10 wrench or socket (typically 17mm for M10 hex heads). For critical applications, a torque wrench is highly recommended.
Installation: Insert the set screw into the aligned holes. For through-hole applications, place a compatible M10 nut on the other side. Tighten gradually, ensuring components are properly aligned.
Torque Application: Tighten to the manufacturer's recommended torque specification for the specific application (refer to project guidelines or engineering standards). Do not over-tighten, as this can damage the screw or the mating material.
Compatibility
Threads: Compatible with standard M10 metric coarse threads (1.5mm pitch).
Nuts: Use with M10 nuts of appropriate strength grade (e.g., Class 8, 10, or 12 to match high tensile screws).
Materials: Suitable for fastening various materials including steel, wood, and plastics, provided they can withstand the clamping force.
Care
Storage: Store unused set screws in a dry environment to maintain the integrity of the zinc plating and prevent corrosion.
Inspection: Before reuse, inspect set screws for any signs of thread damage, bending, or excessive corrosion. Do not reuse damaged fasteners in critical applications.
Cleaning: If fasteners become dirty, clean them with a cloth. Avoid harsh chemicals that could degrade the zinc plating.
