Socket Screws

G-FAST SOCKET FASTENER SERIES

The G-Fast Socket Fastener Series provides OEMs, manufacturers, and engineering teams with a complete range of precision socket-drive fastening solutions. This guide summarizes the core product families, compares available materials, and provides a detailed reference for set screw tip geometries.

1. Socket Fastener Product Family Overview

Socket Head Cap Screws (SHCS)

High-strength cylindrical head design for maximum torque, ideal for machinery, automation, robotics, and heavy-duty assemblies.

Low Head Socket Cap Screws

Reduced-head-height socket cap screws designed for space-constrained assemblies where standard socket head cap screws are too tall.

Button Head Socket Cap Screws

Low-profile, rounded head for clean appearance and safety in housings, guards, electronics, and consumer-facing components.

Flat Head Socket Cap Screws

Countersunk, flush-mount fasteners used in applications requiring smooth surfaces, precision fit, and streamlined design.

Socket Shoulder Bolts (Stripper Bolts)

Precision fasteners with a ground shoulder used for alignment, spacing, and controlled sliding or rotational motion.

Socket Set Screws

Headless, fully threaded fasteners used for locking, positioning, and indexing shafts, collars, gears, and instrumentation components.
