FAQ About Custom Socket Head Cap Screws
What is the difference between socket head cap screws, flat head socket screws and button head socket screws?
Socket head cap screws are used when high clamping force and strength are required. Flat head socket screws are used when the head must sit flush with the surface. Button head socket screws are used when a lower rounded head and better appearance are needed for visible assemblies. If you are not sure which type to choose, you can send us your application or drawing for recommendation.
How do you control the socket drive quality to avoid stripping?
We inspect socket depth, hex drive dimensions, thread accuracy, head size and hardness during production. For high-strength or precision applications, additional inspection requirements can be arranged according to the drawing or project standard.
Can you make socket set screws with different point types?
Yes. We can supply socket set screws with flat point, cone point, cup point and dog point designs. These are commonly used for shafts, collars, pulleys, gears and positioning applications.
Can you customize shoulder diameter and shoulder length for shoulder socket screws?
Yes. For shoulder socket screws, we can customize shoulder diameter, shoulder length, thread size, material and tolerance according to drawings. This is important for pivot, guide, spacer and locating applications.
Do you provide inspection reports or third-party testing?
Yes, we provide inspection reports for each shipment, including basic testing data such as dimensions and mechanical properties.
If required, third-party inspection can also be arranged, such as SGS or TÜV, before shipment.
Can you supply mixed socket screw types in one order?
Yes. We can support mixed orders including socket head cap screws, flat head socket screws, button head socket screws, low head socket screws, socket set screws and shoulder socket screws. This is suitable for distributors, machinery factories and maintenance buyers who need multiple socket fastener types in one shipment.
What is your typical production lead time?
For standard socket head cap screws, production usually takes around 20–40 days. For customized socket head cap screws, it may take longer depending on complexity and tooling requirements.
