STRAIGHT CAPTIVE PIN SHACKLES

Description

Gloma Nautica Straight Captive‑Pin Shackles – Forged AISI 316 Stainless Steel

Gloma Nautica’s Straight Captive‑Pin Shackles combine robust engineering with user‑friendly design, delivering unmatched performance for critical rigging and anchoring tasks. Exclusively forged from AISI 316 marine‑grade stainless steel, these shackles resist saltwater corrosion and mechanical wear—ideal for environments where durability is non-negotiable

Key Features & Benefits:

• AISI 316 Marine‑Grade Construction
  Crafted from high‑quality AISI 316 stainless, these shackles offer superior protection against rust, pitting, and corrosion—resulting in long-lasting structural integrity even in harsh marine settings

• Captive Screw–Eye Pin
  The non‑removable screw‑eye pin is captive to the shackle body, enhancing safety by ensuring the pin remains secured and cannot be lost. The integrated eye facilitates easy installation with hand tools, and the screw mechanism provides reliable resistance against vibration-induced loosening

• Forged for Strength
  Manufactured using precision cold- and hot‑forging techniques, these shackles feature optimal grain alignment for maximum tensile strength and fatigue durability—far exceeding qualities found in cast alternatives regate.lv+6glomanautica.com+6toplicht.com+6.

• Ideal Geometry for Aligned Loads
  Designed in the classic “D” shape, these shackles are most effective when connecting straight-line loads. The shape ensures even load distribution along the shackle body for dependable performance nautos-usa.com+1ebay.com+1.

• Range of Sizes & Load Ratings
  Available in pin diameters from 4 mm (5/32″) to 12 mm (1/2″), each size is rated with certified Working Load Limits (WLL) and break strengths. Example for the 4 mm (101‑I) shackle:

  • Inside width A = 8 mm, length B = 15 mm

  • WLL = 450 kg; Break = ~1,050 kg
    The 1/4″ (103‑I) version can handle a WLL of 1,000 kg and a break load of 1,800 kg

• Maintenance‑Friendly Finish
  The polished stainless finish not only resists environmental wear, but also allows quick inspection, helping to detect deformation early.

• Certified & Traceable Quality
  Each batch is tested and certified by APPLUS in Barcelona, ensuring compliance with international mechanical and safety standards

Typical Applications:
Optimal for halyard attachment, safe lashings, deck fittings, lifelines, towing, block connections, and any scenario requiring secure, vibration‑resistant load connections with aligned geometry.
