Classification of Stainless Steel Fasteners
1. Screws
- Machine Screws (Pan, Flat, Oval, Round, Cheese, Truss Head)
- Self-tapping Screws (Flat, Pan, Hex Washer Head)
- Wood Screws (Flat, Pan, Deck)
- Set Screws (Cup, Cone, Flat, Dog Point)
- Security Screws (Torx, Hex, Spanner Head)
2. Bolts
Bolts are heavy-duty threaded fasteners commonly used with nuts to secure two or more objects together. Types include:
- Hex Bolts: Versatile bolts with hexagonal heads, available in fully threaded or partially threaded variations, ideal for construction and industrial applications.
- Carriage Bolts: Designed with a smooth rounded head and a square neck to prevent rotation when tightened. Suitable for wood-to-metal fastening.
- Eye Bolts: Bolts with a looped head used primarily for lifting or securing cables, available in machinery and lag variations.
- U-Bolts: Shaped in “U” form, these bolts provide secure clamping around pipes or tubes and are available in round bend and square bend options.
- Lag Bolts: Heavy-duty screws with hexagonal heads used for wood or heavy material fastening.
- Flange Bolts: Bolts featuring a built-in washer-like flange to distribute load evenly.
- Shoulder Bolts: Precision bolts with a cylindrical shoulder for alignment or rotational applications.
- Anchor Bolts: Used to anchor structural components to concrete, available in bent and straight configurations.
- Structural Bolts: High-strength bolts for structural steelwork, including tension control (TC) bolts for precise torque control.
3. Nuts
Nuts are used alongside bolts or screws to secure fastened items firmly in place:
- Hex Nuts: Most common nut type, available in standard or heavy-duty designs for general applications.
- Lock Nuts: Designed to resist loosening under vibration or torque, including nylon insert and all-metal types.
- Wing Nuts: Easily tightened or loosened by hand without tools, ideal for applications requiring frequent adjustments.
- Cap Nuts (Acorn Nuts): Closed-end nuts providing a decorative finish and protecting threads from damage.
- Coupling Nuts: Long cylindrical nuts used to join threaded rods or studs.
- Square Nuts: Four-sided nuts offering better resistance to loosening compared to hex nuts.
- Castle Nuts (Slotted Nuts): Used with cotter pins to prevent loosening, commonly in automotive and machinery applications.
- Flange Nuts: Nuts with an integrated washer to distribute load evenly and reduce the risk of loosening.
- Rivet Nuts (Nutserts): Internally threaded inserts providing strong threads in thin or brittle materials.
