Machine Screws — All Head Types

DIN 7985 / DIN 965 / DIN 84 · ISO 7045 / ISO 7046

Description

Machine screws are fully threaded fasteners used with a nut or tapped hole. Available in pan head, countersunk (CSK), cheese head, hex head and button head configurations. Used extensively in electronics, machinery, automotive and general fabrication.

Applications

Electronics & electrical panels · Machinery assembly · Automotive components · Appliances · General fabrication · OEM manufacturing

Screw

Socket Cap Screws & Set Screws

DIN 912 / DIN 916 · ISO 4762 · Grade 12.9

Description

Socket cap screws (Allen bolts) feature a cylindrical head with a hexagonal socket drive — allowing installation in recessed or counter-bored applications. Set screws (grub screws) are headless screws used to lock components onto shafts.

Applications

CNC machinery · Motor shaft locking · Precision engineering · Jigs & fixtures · Hydraulic fittings · Automotive & aerospace

Standards & Grades

Screw

Self-Tapping & Self-Drilling Screws

DIN 7981 / DIN 7504 · Type A · B · AB · C

Description

Self-tapping screws form their own thread in pre-drilled holes in sheet metal, plastic or timber. Self-drilling screws (Tek screws) combine a drill point with thread-forming capability — no pilot hole needed, making installation faster in steel-to-steel and steel-to-timber applications.

Applications

Roofing & cladding · Steel fabrication · HVAC ducting · Electrical enclosures · Automotive trim · General sheet metal

Types & Standards

Type A — Coarse Thread Type B — Fine Thread Type AB — Combo DIN 7981 — Pan Head ST DIN 7982 — CSK Head ST DIN 7504 — Self-Drilling Point #1 to #5 (Drill size) Size: #6 – #14 / 3.5–6.3mm

Anchor

Chemical Anchors — Epoxy & Vinylester

ETA Approved · Cracked & Uncracked Concrete · M8–M39

Description

Chemical anchors use a two-component resin system to bond threaded rods or rebar into concrete, masonry, brick or stone. Suitable for high-load structural applications, close to edges, and in cracked concrete where mechanical anchors cannot be used.

Applications

Structural steel connections · Balustrade fixings · Overhead loading · Rebar starter bars · Masonry & brick · Close-to-edge fixings

Anchor Types & Standards

Epoxy Resin — Maximum Load Vinylester — General Use Polyester — Light Duty ETA 12/0373 Approved Cracked Concrete Rated Rod: CS · HDG · SS316 Size: M8 – M39

Anchor

Mechanical Anchors — Wedge, Sleeve & Drop-In

ETA Approved · Concrete & Masonry · M6–M24

Description

Mechanical anchors use expansion to grip the substrate — no mixing, no curing time. Wedge anchors expand when the nut is tightened; sleeve anchors expand when the screw is driven; drop-in anchors are set by a tool. Suitable for medium-load applications in solid concrete and block.

Applications

Machinery fixing to floors · Handrail & stair posts · Pipe supports · Electrical trunking · HVAC equipment · Mezzanine floors
