Socket Head Cap Screws
High-strength internal-hex screws to ISO 4762 / DIN 912. Ideal for compact, high-clamp joints. Offered in 12.9 black, zinc-plated alloy, and stainless A2/A4; coarse and fine pitch available.
Flat Head Socket Cap Screws
Countersunk (90°) heads to ISO 10642 / DIN 7991 for flush surfaces in machine covers, robotics and frames. Choose stainless A4 in corrosive or marine environments.
Socket Grub (Set) Screws
Tip styles DIN 913 (flat), 914 (cone), 915 (dog), 916 (cup) for shafts, collars and pulleys. Case-hardened where applicable for bite and holding power.

Low-profile domed heads to ISO 7380 for enclosures and guards where snag-resistant finishes are needed. Available in alloy steel and stainless A2/A4.
CSK Socket Head Cap Screws
Countersunk socket caps (CSK) for flush assemblies when higher strength is required than standard machine screws. Use with matching countersinks and verify minimum sheet thickness.
Flange Button Head Socket Screws
Integrated washer face to ISO 7380-2 spreads load and saves an extra washer—great for thin plates and plastics.
Low Head Socket Cap Screws
Reduced head height per DIN 7984 for tight clearance builds. Check required strength and recess size vs. tool access.
Socket Head Shoulder Screws
Precision shoulder (stripper) screws to ISO 7379 for bearing surfaces, linkages and tooling. Shoulder Ø/fit tolerance ensures accurate sliding/rotational movement.
