Compact high-strength fastening for industrial assemblies

Socket head cap screws are machine screws featuring a cylindrical head and an internal hexagonal drive. Their compact head geometry makes them suitable for applications where conventional hex-head fasteners may not provide sufficient clearance.

These fasteners are commonly used in machinery, equipment, fabricated assemblies, tooling, piping support systems and other mechanical applications requiring a compact and secure bolted connection.

Socket head cap screws can be supplied in carbon steel, alloy steel and stainless steel grades. Material and strength selection depends on the mechanical requirements and service environment.

Rhevon can source socket head cap screws according to the required diameter, length, thread, material grade, finish and quantity.

FREQUENTLY ASKED QUESTIONS

Socket Head Cap Screw FAQ

Common procurement questions about socket head cap screws, grades, dimensions and applications.

Socket head cap screws are commonly used in machinery, equipment, tooling, fabricated assemblies and other mechanical applications where a compact fastener head and internal hex drive are advantageous.

The internal hex drive allows the screw to be tightened using a hex key or suitable internal-hex tool. The cylindrical head also provides a compact installation profile where surrounding clearance is limited.

Yes. Stainless steel socket head cap screws can be sourced in grades such as SS304 and SS316, depending on the required size, quantity and application.

A typical enquiry should include diameter, length, thread type, material or property class, applicable dimensional standard, surface finish and quantity. A drawing or specification can also be provided where available.

Yes. Socket head cap screws can be included in a mixed RFQ along with pipe fittings, flanges, gaskets and other fasteners.
