Manufactured from 316-grade stainless steel, it provides strong corrosion resistance for repeated saltwater use while maintaining the rigidity needed from a full-size speargun shaft. The 5\/16in diameter gives the shaft a solid, substantial profile, while twin loading notches provide compatibility with traditional speargun wishbone systems. Available across multiple shaft lengths, it can be matched to a range of Undersee spearguns and other compatible setups where the correct shaft diameter, length and trigger engagement are required.\u003c\/p\u003e\n\u003ch2\u003eUndersee 5\/16 SS Threaded Spear Shaft Key Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e316-Grade Stainless Steel:\u003c\/strong\u003e Marine-grade stainless steel construction provides excellent resistance to corrosion and surface degradation from saltwater exposure, making it well suited to regular spearfishing use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5\/16in Shaft Diameter:\u003c\/strong\u003e The substantial 5\/16in diameter provides a strong, rigid shaft profile commonly used with traditional Australian speargun setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreaded Tip Configuration:\u003c\/strong\u003e Threaded front end allows the shaft to be paired with compatible screw-on spear tips and terminal components, giving divers the flexibility to configure the shaft for their existing setup.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwin Loading Notches:\u003c\/strong\u003e Two notches provide loading positions for compatible wishbones and traditional rubber-powered speargun systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiple Length Options:\u003c\/strong\u003e Available from shorter 24in configurations through to 60in shafts, allowing the correct overall length to be matched to different speargun sizes and applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarine-Ready Construction:\u003c\/strong\u003e Stainless steel material is chosen specifically for harsh saltwater environments where corrosion resistance and long-term durability matter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplacement Or Setup Component:\u003c\/strong\u003e Suitable for replacing a worn or damaged shaft, or for configuring a compatible speargun with a traditional threaded spear shaft.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraditional Undersee Compatibility:\u003c\/strong\u003e Designed around Undersee-style speargun systems, with compatibility dependent on the selected shaft length, trigger mechanism and speargun configuration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Undersee","offers":[{"title":"24 inches","offer_id":44408225202310,"sku":"9325132000416","price":39.99,"currency_code":"AUD","in_stock":true},{"title":"36 inches","offer_id":44408225235078,"sku":"9325132000478","price":44.99,"currency_code":"AUD","in_stock":false},{"title":"40 inches","offer_id":44408225267846,"sku":"9325132000430","price":49.99,"currency_code":"AUD","in_stock":true},{"title":"48 inches","offer_id":44408225300614,"sku":"9325132000447","price":54.99,"currency_code":"AUD","in_stock":true},{"title":"54 inches","offer_id":44408225333382,"sku":"9325132000454","price":59.99,"currency_code":"AUD","in_stock":true},{"title":"60 inches","offer_id":44408225366150,"sku":"9325132000461","price":64.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/1285\/files\/undersee_516_ss_threaded_spear_shaft_9325132000447_adreno_1.jpg?v=1790137439","url":"https:\/\/adreno.com.au\/products\/undersee-5-16-ss-threaded-spear-shaft","provider":"Adreno - Ocean Outfitters","version":"1.0","type":"link"}
