Product description

Compiled from the existing technical description of this product on this site

The hex socket countersunk screw uses a precision countersunk design; after tightening the head is flush with the mating surface and takes no extra height, which suits areas that must be flat with no protrusion. The hex socket drive distributes load evenly and withstands high tightening torque without slipping; the surface finish is fine and clean.

Technical Features
90° countersunk structure, flush with the mating surface after tighteningHex socket drive: high torque transfer and slip resistancePrecise countersink angle, excellent seating in the countersunk holeHigh-strength alloy steel with high load capacityUniform and fine surface finish, clean appearance
Applications
Machine tools and fixturesClamping of moulds and cutting toolsMoving parts in automation equipmentPrecision instrument structures

FAQ

Material, standards, surface treatment and installation points for this model; the data comes from the specification table on this page and from the national standards cited in the answers.

Q1What material is the Hex Socket Countersunk Screw made of, and what strength level does it achieve?

Marked in the specification table on this page: material is high-strength alloy steel. Material certificates and mechanical property test reports can be supplied with the goods; batch acceptance follows the data above.

Q2To which standards is the Hex Socket Countersunk Screw manufactured and inspected?

Standards marked in the specification table on this page: hex socket countersunk head screw GB/T 70.3 (ISO 10642); mechanical properties GB/T 3098.1 (ISO 898-1). Dimensional inspection reports can be supplied with the shipment; batch acceptance follows the standards above and the drawings agreed by both parties.

Q3What surface treatments are available for the Hex Socket Countersunk Screw, and how to choose?

Surface treatment marked in the specification table on this page: black oxide / zinc plated (optional). Each coating differs in appearance, corrosion resistance and cost; choose according to the service environment and order agreement.

Q4What applications is the Hex Socket Countersunk Screw suitable for?

Typical applications listed on this page: machine tools and fixtures; mould and tool clamping; moving parts of automation equipment; precision instrument structures. Overview: the hex socket countersunk screw uses a precision countersunk design; after tightening the head is completely flush with the mating surface and takes no extra height, which suits areas that must be flat with no protrusion.

Q5What does the 6g thread tolerance of the Hex Socket Countersunk Screw mean?

6g is the standard tolerance class for external threads (GB/T 197 / ISO 965-1). It defines the manufacturing tolerance range for the pitch diameter and major diameter, balancing smooth engagement against manufacturing economy; the mating internal thread is usually 6H. All threads in this series are inspected to 6g. (Applies to model "hex socket countersunk screw".)
