This is not possible, as there is a rubber ring on the other side of the hole. This naturally allows for some play because it is flexible. If you continue to tighten it, the flexibility will eventually be exhausted and too much tension will be placed on the wing nut. This could damage the groove in the wing nut. Our advice is therefore simply to tighten it until it feels \u2018secure\u2019 (you\u2019ll feel resistance); that\u2019s sufficient.<\/p>","protected":false},"excerpt":{"rendered":"<p>Wing nut (complies with food safety standards) used to secure a Black Berkey or BOROUX Foundation\u2122 Black filter cartridge in the system<\/p>","protected":false},"featured_media":767,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[1034,1035],"product_cat":[163,181,110],"product_tag":[112,573,617,113,457,165,41,578,620,124,167,125],"class_list":["post-741","product","type-product","status-publish","has-post-thumbnail","product_brand-berkey","product_brand-boroux","product_cat-waterfilter-accessoires","product_cat-waterfilter-elementen","product_cat-waterfilters","product_tag-berkey","product_tag-berkey-systemen","product_tag-black-bekrey-filterelementen","product_tag-black-berkey","product_tag-boroux","product_tag-drinkwater","product_tag-kraan","product_tag-standaard","product_tag-vleugelmoer","product_tag-waterfilter","product_tag-waterfilters","product_tag-waterzuivering","pa_merk-berkey","pa_merk-boroux","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"bundled_by":[],"bundle_stock_status":"instock","bundle_stock_quantity":null,"bundle_virtual":false,"bundle_layout":"","bundle_add_to_cart_form_location":"","bundle_editable_in_cart":false,"bundle_sold_individually_context":"","bundle_item_grouping":"","bundle_min_size":"","bundle_max_size":"","bundle_price":[],"bundled_items":[],"bundle_sell_ids":[880,740],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 -
