Self-Drilling Screws

Why 410 Self-Drilling Screws?

410 Self-Drilling Screws are bright hardened. This allows them to drill through steel and gives them a shiny stainless steel appearance.

Self-drilling screws are slightly magnetic which allows them to attach to magnetic hex drivers. This is great for one hand installation. This saves time.

Self drillers are used in mildly corrosive environments, otherwise 1000-hour coating can be applied for more corrosive applications.

Uses of EPDM Bonded Sealing Washers

Features of EPDM bonded washers

EPDM, or ethylene propylene diene monomer rubber is a synthetic rubber known for its outstanding use of:

Neoprene (Neo) Washers

In addition to EPDM washers, we also offer Neoprene washers. Neoprene, more formally known as polychloroprene (PC), is a synthetic rubber quite similar to EPDM. Neoprene washers are generally used in Interior applications, away from UV rays. Neoprene is highly resistant to chemicals and oils. These washers do a great job insulating against heat and moisture. These are a lower resistance range and less flexible at low temperatures therefore not recommended for direct contact with petrochemicals.
